Example 1

Embodiments provide an oral cleaning device that provides cleaning functionality to a user's oral cavity. In some embodiments, the oral cleaning device may be an electric toothbrush.

As shown in fig. 1 and 2, the oral cleaning device may include a handle 100, a brush bar 200, a brush head 300, and an image acquisition mechanism 400.

Wherein one end of the brush bar 200 may be connected to the handle 100. The brush head 300 is detachably connected to the end of the brush bar 200 remote from the handle 100. During the use of the oral cleaning device, the handle 100 drives the brush bar 200 to vibrate, and the brush bar 200 drives the brush head 300 to vibrate, so as to provide a cleaning function.

Referring again to fig. 3 and 5, the image acquisition mechanism 400 may be used to acquire image information in the user's mouth so that the user knows the condition in the mouth. When the pathological changes such as saw teeth or inflammation appear in the oral cavity of the user, the user can also know and treat the pathological changes in time conveniently. In an embodiment, the image capture mechanism 400 is slidably mounted in the brush bar 200, and the image capture mechanism 400 is retractable relative to an end of the brush bar 200 remote from the handle 100. Accordingly, the image acquisition mechanism 400 may include a contracted state 401 and an extended state 402.

It is understood that when the image capturing mechanism 400 is in the contracted state 401, the image capturing mechanism 400 may be housed in the brush bar 200. When the image capture mechanism 400 is in the extended state 402, the image capture mechanism 400 may extend away from an end of the handle 100 relative to the brush bar 200.

During use of the oral cleaning device, when the user does not need to use the image capturing mechanism 400, the image capturing mechanism 400 can be housed in the brush bar 200 even if the image capturing mechanism 400 is in the contracted state 401. Therefore, the image acquisition mechanism 400 can be hidden, discomfort caused by monitoring is avoided for the user, and privacy protection of the user is improved. When the user needs to use the image acquisition mechanism 400, the brush head 300 can be detached from the brush rod 200, and the image acquisition mechanism 400 is switched from the contracted state 401 to the extended state 402, so that the image acquisition mechanism 400 can acquire the image information in the oral cavity of the user, and in addition, the brush rod 200 does not need to extend into the oral cavity of the user, so that uncomfortable feeling caused when the brush rod 200 extends into the oral cavity of the user due to large volume is avoided.

Compared with the prior art, the image acquisition mechanism 400 is hidden in the brush rod 200, the size of the conventional brush head 300 is not required to be changed, and discomfort brought to a user due to the increase of the volume of the brush head 300 can be avoided. Therefore, the user privacy safety is improved, and the comfort of the user when using the oral cavity cleaning device can be ensured.

Example two

In an embodiment, there is provided an oral cleaning device, further comprising, based on the first embodiment:

as shown in fig. 1 and 2, the handle 100 may include a main housing 110, a main board 120, and a deck assembly 130. The main housing 110 has a hollow interior and may define a mounting cavity 111. In an embodiment, the motherboard 120 and the engine assembly 130 are both mounted within the mounting cavity 111 of the main housing 110.

It will be appreciated that the deck assembly 130 may include structural elements such as a vibration motor and a power source. Wherein, the output shaft 131 of the vibration motor may be penetrated at one end of the main housing 110 and protruded with respect to one end of the main housing 110. In the embodiment, one end of the brush rod 200 may be sleeved at the protruding end of the output shaft 131 relative to the main housing 110, and the brush rod 200 and the output shaft 131 may be bonded by waterproof glue, so that on one hand, a sealing waterproof effect may be achieved. On the other hand, the vibration damping between the output shaft 131 and the brush bar 200 can also be reduced. In addition, the vibration motor and the power supply are electrically connected to the main board 120, and the operation of the vibration motor can be controlled by the main board 120.

As shown in fig. 1 and 2, the handle 100 further includes a bell jar 140 and a decorative piece 150.

The bell jar 140 may be sleeved on the output shaft 131, and the bell jar 140 may be located at a connection between the output shaft 131 and the main housing 110. On the one hand, the sealing waterproof function of the junction of the output shaft 131 and the main housing 110 can be achieved by the bell housing 140. On the other hand, the bell housing 140 may reduce the transmission of vibration between the output shaft 131 and the main housing 110, thereby achieving a vibration damping effect.

The decoration 150 may be sleeved on one end of the main housing 110 near the brush bar 200, and may decorate the handle 100, thereby improving the aesthetic property of the handle 100.

As shown in fig. 3 and 5, the inside of the brush bar 200 may be provided with a fitting hole 210 for installing the image capturing mechanism 400. The mounting hole 210 may be a through hole, that is, both ends of the mounting hole 210 are open structures. In an embodiment, the image capture mechanism 400 is slidably mounted in the mounting hole 210.

Referring again to fig. 2, in some embodiments, the mounting holes 210 may be generally circular through holes. That is, the shape of the fitting hole 210 may be substantially circular perpendicular to the axial direction of the oral cleaning device. The axial direction of the oral cavity cleaning device can refer to the extending direction of the axis L.

Referring to fig. 1 and 6, the overall shape of the image capturing mechanism 400 may be substantially cylindrical and adapted to the mounting hole 210.

In an embodiment, image capture mechanism 400 may include a carrier assembly 410 and an image capture member 420. Wherein the carrier assembly 410 may include a base 411 and a transparent cover 412. In an embodiment, the transparent cover 412 may be a casing structure with one end open. One end of the transparent cover 412 provided with an opening can be sleeved at one end of the base 411 far away from the handle 100, and positioning connection can be realized between the transparent cover 412 and the base 411 through positioning strips and positioning grooves, so that the transparent cover 412 can be prevented from rotating randomly relative to the base 411. In some embodiments, the positioning strips may be protruding from the circumference of the base 411, and the positioning slots may be formed on the inner wall of the transparent cover 412.

In other embodiments, the transparent cover 412 and the base 411 may be fixedly connected by adhesion, screwing, or tight fitting.

In the embodiment shown in fig. 2 and 6, the image capturing element 420 may be fixedly mounted within the transparent cover 412 by a bracket 450. Specifically, the image capturing element 420 may be fixedly mounted on the bracket 450, and the bracket 450 may be fixed in the transparent cover 412 by a structural limitation. In an embodiment, the bracket 450 may abut against an end surface of the base 411 away from the end of the handle 100.

In other embodiments, the bracket 450 may be secured within the transparent cover 412 by adhesive, snap fit, interference fit, or the like.

Referring again to fig. 5, in some embodiments, the image capturing element 420 may be a camera. The light entry side of the image capture member 420 may be opposite the circumferential side wall of the transparent cover 412. Accordingly, when the image capturing mechanism 400 is in the extended state 402, external light can be projected onto the image capturing element 420 through the circumferential sidewall of the transparent cover 412, and the image capturing element 420 can capture image information.

As shown in fig. 1 and 6, the image capturing mechanism 400 further includes a light compensating lamp 430, and the light compensating lamp 430 may also be fixedly mounted on the bracket 450. In an embodiment, the bracket 450 is further fixedly provided with a lens 440, and the lens 440 may be opposite to the light emitting side of the light compensating lamp 430. In the process of using the image capturing mechanism 400, the brightness in the oral cavity of the user can be improved by the light compensating lamp 430, so that the image capturing element 420 can obtain clear image information, and the user can conveniently view the clear image information. In some embodiments, the light compensating lamp 430 may be located on a side of the image capturing member 420 near the base 411.

Referring again to fig. 2 and 5, in an embodiment, when the image capturing mechanism 400 is in the extended state 402, the transparent cover 412 may be fully protruding with respect to the end of the brush bar 200 remote from the handle 100. Accordingly, the image capturing element 420 and the light compensating lamp 430 can be exposed relative to the brush holder 200, so that the light compensating lamp 430 can project light to the oral cavity of the user, and the image capturing element 420 can be ensured to capture the image information of the oral cavity of the user.

In other embodiments, when the image capturing mechanism 400 is in the extended state 402, a portion of the structure of the transparent cover 412 may protrude from an end of the brush bar 200 remote from the handle 100, and at least a position of the transparent cover 412 opposite the image capturing element 420 and the light filling lamp 430 may be exposed to the brush bar 200.

It will be appreciated that the transparent cover 412 may provide dust and water protection for the image capture member 420 and the light replenishment light 430. On the one hand, the interference of water vapor and dust on the operation of the image acquisition member 420 can be avoided, and the definition of the image acquired by the image acquisition member 420 is ensured. On the other hand, the service lives of the image pickup member 420 and the light compensating lamp 430 may be prolonged.

In addition, when the image capturing mechanism 400 is in the contracted state 401, the transparent cover 412 can be completely contained in the brush bar 200. Thus, the abrasion of the transparent cover 412 during the oral cleaning process can be avoided, and the image acquisition member 420 can acquire a clear image through the transparent cover 412.

As shown in fig. 5 to 7, further, at least one stopper 4111 is further disposed on the base 411 at a circumference of an end far from the transparent cover 412, and the stopper 4111 may be disposed in a protruding manner along a radial direction of the base 411. Correspondingly, at least one limiting groove 220 can be formed on the inner wall of the assembly hole 210, and the limiting groove 220 can be matched with the limiting block 4111. In an embodiment, the limit slot 220 may extend in the axial direction of the oral cleaning device.

In some embodiments, two symmetrical stoppers 4111 may be provided on the base 411 in a protruding manner. Correspondingly, two symmetrical limiting grooves 220 can be formed on the inner wall of the assembly hole 210. The two limiting blocks 4111 can be slidably assembled in the two limiting grooves 220 in a one-to-one correspondence manner. That is, the stopper 4111 can slide in the stopper groove 220 in the axial direction of the oral cleaning device. Therefore, under the cooperation of the limiting block 4111 and the limiting groove 220, the rotation of the image capturing mechanism 400 relative to the brush holder 200 can be limited. Therefore, when the image capturing mechanism 400 slides relative to the brush holder 200, the probability of jamming between the image capturing mechanism 400 and the brush holder 200 can be reduced, and the image capturing mechanism 400 can slide in the assembly hole 210 more smoothly.

In other embodiments, one, three, or five equal number of stoppers 4111 may be provided on the base 411. Correspondingly, the inner wall of the assembly hole 210 may be provided with one, three or five equal number of limiting grooves 220, and the number of the limiting grooves 220 may be equal to the number of the limiting blocks 4111.

Referring to fig. 2, 3, 8 and 9, in the embodiment, at least one end of the limiting groove 220 away from the handle 100 is a closed structure. Accordingly, an end of the limiting groove 220 away from the handle 100 may include a first abutment wall 230, and the first abutment wall 230 faces the handle 100. When the image capturing mechanism 400 is in the extended state 402, a side of the stopper 4111 away from the handle 100 may abut against the first abutment wall 230. Thus, the image capturing mechanism 400 may be restricted from completely disengaging the brush bar 200 during the transition of the image capturing mechanism 400 from the retracted state 401 to the extended state 402.

In some embodiments, the end of the limiting slot 220 near the handle 100 is open to an open configuration. In other embodiments, the end of the limiting slot 220 near the handle 100 may be a closed structure.

As shown in fig. 3, 5 and 6, the image capturing mechanism 400 further includes a first sealing ring 460, where the first sealing ring 460 may be sleeved on the circumference of the base 411. Along the axial direction of the oral cleaning device, the first sealing ring 460 may be located between the stopper 4111 and the transparent cover 412. Along the radial direction of the base 411, a portion of the first sealing ring 460 may be embedded in the base 411, so as to prevent the first sealing ring 460 from sliding randomly relative to the base 411. In addition, the side of the first sealing ring 460 away from the base 411 may protrude with respect to the circumferential sidewall of the base 411 and abut against the inner wall of the assembly hole 210. In an embodiment, the first sealing ring 460 is compressible between the base 411 and the inner wall of the assembly hole 210.

Referring again to fig. 2, it is understood that when the image capturing mechanism 400 is in the extended state 402, the first sealing ring 460 may be located on a side of the limiting groove 220 away from the handle 100. Accordingly, the circumferential side wall of the first sealing ring 460 can be completely attached to the inner wall of the assembly hole 210, so as to achieve a sealing and waterproof effect. Meanwhile, under the action of friction resistance between the first sealing ring 460 and the inner wall of the assembly hole 210, the image acquisition mechanism 400 can be prevented from being optionally retracted into the assembly hole 210, that is, the image acquisition mechanism 400 is prevented from being optionally switched from the extended state 402 to the contracted state 401.

Of course, in other embodiments, a stop button assembly may be disposed between the end of the inner wall of the mounting hole 210 away from the handle 100 and the image capturing mechanism 400 to prevent the image capturing mechanism 400 from being retracted at will.

As shown in fig. 2 to 5, when the brush head 300 is coupled to the brush bar 200, one end of the brush head 300 for coupling to the brush bar 200 may be inserted into one end of the assembly hole 210 remote from the handle 100. In an embodiment, the end of the brush head 300 near the brush bar 200 may include a first connection portion 310, and the first connection portion 310 may be located on a circumferential sidewall of the end of the brush head 300 near the brush bar 200. Correspondingly, the end of the brush bar 200 remote from the handle 100 may include a second connection portion 240, and the second connection portion 240 may be located on an inner wall of the mounting hole 210 remote from the end of the handle 100. When the brush head 300 is connected with the brush bar 200, the first connecting portion 310 can be detachably connected with the second connecting portion 240.

In some embodiments, the first connecting portion 310 may be a clip protruding from a circumferential sidewall of the brush bar 200. The second connection portion 240 may be a slot formed on the inner wall of the mounting hole 210. When the brush head 300 is connected with the brush rod 200, the first connecting portion 310 can be clamped in the second connecting portion 240, so that the brush head 300 can be prevented from being separated from the brush rod 200 at will.

In other embodiments, the first connecting portion 310 may be a clamping groove formed on a circumferential side wall of the brush holder 200, and the second connecting portion 240 may be a clamping block protruding from an inner wall of the assembly hole 210.

In an embodiment, the first connection part 310 and the second connection part 240 may be provided in one pair, two pairs, three pairs, or five pairs, etc., as needed. In addition, along the circumferential direction of the brush rod 200, the second connecting portion 240 may be disposed offset from the limiting groove 220.

In other embodiments, the first connecting portion 310 may also be external threads formed on a circumferential sidewall of the brush head 300. The second connection portion 240 may also be an internal thread formed on the inner wall of the fitting hole 210.

Further, as shown in fig. 3, the oral cleaning device also includes a second seal ring 600. The second sealing ring 600 may be sleeved on the circumference of the end of the brush head 300 near the brush rod 200. In an embodiment, the second seal 600 may be used to provide a sealing connection between the brush head 300 and the brush bar 200 to provide a sealing waterproof function.

Referring again to fig. 2, 4 and 5, in some embodiments, the second sealing ring 600 may be located on a side of the first connecting portion 310 remote from the handle 100. The second seal ring 600 may be partially embedded in the brush head 300 in the radial direction of the brush head 300, so that the second seal ring 600 may be prevented from sliding with respect to the brush head 300. In addition, the side of the second seal 600 remote from the brush head 300 may protrude relative to the circumferential side wall of the brush head 300. When the brush head 300 is connected with the brush rod 200, the second sealing ring 600 may be inserted into the assembly hole 210 of the brush rod 200 along with the brush head 300, and a side of the second sealing ring 600 away from the brush head 300 may abut against an inner wall of the assembly hole 210. That is, the second seal ring 600 may be compressed between the brush head 300 and the inner wall of the assembly hole 210 to achieve a sealed connection between the brush head 300 and the brush rod 200.

As shown in fig. 2 and 3, further, the oral cleaning device also includes a drive assembly 500 operable to drive the image capture mechanism 400 toward an end of the brush bar 200 remote from the handle 100. In some embodiments, the drive assembly 500 may include a first magnetic member 510 and a second magnetic member 520, and the polarity of the first magnetic member 510 and the polarity of the second magnetic member 520 are opposite, i.e., the first magnetic member 510 and the second magnetic member 520 may attract each other.

Wherein, the first magnetic element 510 can be mounted on one end of the brush head 300 near the brush bar 200. In an embodiment, the first magnetic member 510 may be embedded in an end of the brush head 300 near the brush rod 200, and an end wall of the first magnetic member 510 near the end of the handle 100 may be flush with an end wall of the brush head 300 near the end of the handle 100.

Referring again to fig. 6, the second magnetic member 520 may be fixedly mounted in the transparent cover 412. Specifically, the second magnetic member 520 may be located at an end of the bracket 450 away from the base 411, and the second magnetic member 520 abuts between the bracket 450 and an end wall of the transparent cover 412 at an end away from the handle 100.

Referring to fig. 5 again, when the brush head 300 is connected to the brush holder 200, the end of the brush head 300 with the first magnetic member 510 may abut against the end of the image capturing mechanism 400 away from the handle 100. When the image capturing mechanism 400 is needed, the brush head 300 can be detached from the brush holder 200, and in the process of detaching the brush head 300 from the brush holder 200, the image capturing mechanism 400 can extend out of the brush holder 200 under the magnetic attraction of the first magnetic member 510 and the second magnetic member 520, i.e. the image capturing member 420 can be synchronously switched from the contracted state 401 to the extended state 402. When the image capturing mechanism 400 is in the extended state 402, the magnetic attraction between the first magnetic member 510 and the second magnetic member 520 can be overcome to separate the brush head 300 from the image capturing mechanism 400, so that the user can extend the end of the image capturing mechanism 400 provided with the image capturing member 420 and the light compensating lamp 430 into the oral cavity.

In an embodiment, the magnetic attraction force between the first magnetic member 510 and the second magnetic member 520 may be greater than the friction resistance between the image capturing mechanism 400 and the inner wall of the assembly hole 210, so as to smoothly pull out part of the structure of the image capturing mechanism 400 from the brush rod 200.

As shown in fig. 1 to 3 and fig. 6, the image capturing element 420 and the light compensating lamp 430 are electrically connected to the main board 120. In some embodiments, the image pickup member 420 and the light compensating lamp 430 may be electrically connected with the main board 120 through the flexible flat cable 700. Specifically, one end of the flexible flat cable 700 may be positioned within the mounting cavity 111 and connected to the motherboard 120. The other end of flexible flat cable 700 may extend into image capture mechanism 400 and connect with image capture member 420 and light supplement lamp 430.

In an embodiment, the protruding end of the output shaft 131 opposite to the main housing 110 may be provided with a routing hole 1311, and the flexible flat cable 700 may extend from the handle 100 through the routing hole 1311. In addition, the base 411 of the image capturing mechanism 400 may also be provided with a wire hole 4112 for the flexible flat cable 700 to pass through. It will be appreciated that the length of soft wire 700 may meet the telescoping requirements of image capture mechanism 400.

Example III

In embodiments, an oral cleaning device is provided, which differs from the second embodiment in that:

as shown in fig. 3, 5 and 10, the driving assembly 500 may include a resilient member 530. In an embodiment, one end of the elastic member 530 may extend into the routing hole 1311 of the output shaft 131. The inner wall of the wiring hole 1311 far away from the end of the image capturing mechanism 400 may be fixedly provided with a clamping ring 160, and the elastic member 530 may be abutted against the end of the clamping ring 160 near the image capturing mechanism 400. The other end of the elastic member 530 away from the snap ring 160 may abut against one end of the base 411 away from the transparent cover 412.

When the image capturing mechanism 400 is in the contracted state 401, the elastic member 530 may be in a compressed state. When the image capturing mechanism 400 is in the extended state 402, the elastic member 530 may be in a compressed or naturally extended state. In an embodiment, the force applied by the elastic member 530 to the image capturing mechanism 400 may be always greater than the frictional resistance between the image capturing mechanism 400 and the inner wall of the mounting hole 210. Thus, it is ensured that the elastic member 530 can smoothly push out part of the structure of the image capturing mechanism 400 from the brush bar 200. Of course, when the image capturing mechanism 400 is in the extended state 402, the elastic member 530 can also provide a supporting function for the image capturing mechanism 400, so as to further prevent the image capturing mechanism 400 from being optionally retracted into the brush bar 200.

In some embodiments, the resilient member 530 may be a spring. Accordingly, soft ribbon wire 700 may pass through spring 530.

In other embodiments, the elastic member 530 may be a spring or a flexible column.

Example IV

In embodiments, an oral cleaning device is provided, which differs from the second embodiment in that:

as shown in fig. 11, the driving assembly 500 may include a first magnetic member 510, a second magnetic member 520, and an elastic member 530 at the same time. In the embodiment, the first magnetic member 510 and the second magnetic member 520 may be mounted in the same manner as in the second embodiment. The elastic member 530 may be installed in the same manner as in the third embodiment.

Referring to fig. 2, 3 and 5, in the process of switching the image capturing mechanism 400 from the contracted state 401 to the extended state 402, the elastic member 530 cooperates with the first magnetic member 510 and the second magnetic member 520 to jointly drive the image capturing mechanism 400 to extend from the end of the brush bar 200 away from the handle 100.

In an embodiment, the sum of the magnetic attraction force between the first magnetic member 510 and the second magnetic member 520 and the force applied to the image capturing mechanism 400 by the elastic member 530 may be always greater than the frictional resistance between the image capturing mechanism 400 and the inner wall of the assembly hole 210. Thus, it is ensured that the driving assembly 500 can smoothly push the image capturing mechanism 400 to protrude from the end of the brush bar 200 away from the handle 100.

Accordingly, the magnetic attraction force between the first magnetic member 510 and the second magnetic member 520 may be smaller than, equal to, or greater than the frictional resistance between the image capturing mechanism 400 and the inner wall of the fitting hole 210. The force applied to the image capturing mechanism 400 by the elastic member 530 may be smaller than, equal to, or greater than the frictional resistance between the image capturing mechanism 400 and the inner wall of the fitting hole 210.

Example five

In embodiments, an oral cleaning device is provided, which differs from the second embodiment in that:

as shown in fig. 11 to 14, the projection of the end of the base 411 away from the transparent cover 412 is non-circular in a plane perpendicular to the axial direction of the oral cleaning device. The non-circular structural section of the base 411 may be referred to as a limiting section 4113.

Referring again to fig. 2, the mounting hole 210 may include a first step hole 211 and a second step hole 212 in communication, and the first step hole 211 may be positioned closer to the handle 100 than the second step hole 212. In some embodiments, the projection of the inner wall of the first step aperture 211 may also be non-circular in a plane perpendicular to the axial direction of the oral cleaning device, and the projection of the inner wall of the first step aperture 211 may coincide with the circumferential edge of the base 411 projected away from the end of the transparent cover 412. Thus, a positive fit between the base 411 and the brush bar 200 can be achieved, preventing the base 411 from rotating relative to the brush bar 200 about the axis L of the oral cleaning device.

In some embodiments, the first seal ring 460 may be sleeved on the limiting segment 4113, and a circumference of the first seal ring 460 may protrude relative to a circumferential sidewall of the limiting segment 4113. In an embodiment, a side of the first sealing ring 460 away from the base 411 may abut against an inner wall of the first step hole 211 to achieve sealing between the image capturing mechanism 400 and the brush rod 200. It can be appreciated that, through the limit fit between the base 411 and the brush rod 200, the base 411 can be prevented from driving the first sealing ring 460 to rotate. The tightness of the connection between the base 411 and the brush bar 200 can be ensured during the extension and retraction of the image acquisition mechanism 400.

In some embodiments, the projection of the stop segment 4113 and the projection of the inner wall of the first step aperture 211 may each be elliptical in a plane perpendicular to the axial direction of the oral cleaning device. Along the extending direction of the long axis of the limiting segment 4113, the limiting segment 4113 may protrude with respect to the circumference of the base 411 for connecting to one end of the transparent cover 412. The extending direction of the long axis of the limiting segment 4113 may refer to the extending direction of the maximum diameter of the limiting segment 4113. In the embodiment, the limiting segment 4113 is configured to be elliptical, and the first sealing ring 460 is installed on the limiting segment 4113, so that the tightness of the image capturing mechanism 400 relative to the brush rod 200 during expansion and contraction can be ensured, and the waterproof effect can be ensured.

In other embodiments, portions of the stop segment 4113 circumferentially may protrude relative to the circumference of the base 411 for attachment to one end of the transparent cover 412.

In other embodiments, the projection of the spacing segment 4113 and the projection of the inner wall of the first step aperture 211 may be non-circular, such as quadrilateral, pentagonal, or hexagonal, in a plane perpendicular to the axial direction of the oral cleaning device.

Referring again to fig. 3 and 5, in some embodiments, the second step holes 212 may be circular holes. The diameter of the second-stage holes 212 may be smaller than the long axis (i.e., the maximum diameter) of the first-stage holes 211. Accordingly, a second abutment wall 250 may be formed at the junction of the first step hole 211 and the second step hole 212. When the image capturing mechanism 400 is switched from the contracted state 401 to the extended state 402, the second abutment wall 250 may abut against a side of the limiting segment 4113 away from the handle 100, so as to prevent the image capturing mechanism 400 from being disengaged from the brush bar 200.

It is understood that in other embodiments, when the stop segment 4113 and the first step bore 211 are other non-circular shapes, the maximum diameter of the first step bore 211 may refer to the diameter of the circumscribed circle of the first step bore 211.

In addition, the second connecting portion 240 of the brush bar 200 for connecting with the brush head 300 may be disposed on the inner wall of the second hole 212.
