For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to the drawings, an embodiment of the present application provides a powered toothbrush head 100 including a head body 10, a bristle set 20, and a first trigger switch 30. Electric toothbrush head 100 of the present application is used for electric toothbrush 200, electric toothbrush 200 further includes electric toothbrush body 210, and electric toothbrush head 100 can be connected to electric toothbrush body 210.

The brush head body 10 comprises a first accommodating cavity 11 with an installation opening formed in one side, the bristle part 20 is installed at the installation opening, and the first trigger switch 20 is arranged in the first accommodating cavity 11. Wherein the bristle part 20 can move between a first position and a second position relative to the brush head body 10 under the action of external force, the first trigger switch 20 can be separated from the bristle part 20 when the bristle part 20 is in the first position and is triggered when the bristle part 20 is in the second position, and the first trigger switch 20 can send an alarm signal when being triggered.

In the embodiment of the present application, the alarm signal can be responded to by the alarm 40, thereby causing the alarm 40 to issue an alarm notice. Specifically, powered toothbrush head 100 includes warning member 40, and in other embodiments, powered toothbrush body 210 includes warning member 40, without limitation. In some embodiments, the alarm 40 is one or any combination of an alarm light, a buzzer, or a vibrating component, and is not limited herein. Specifically, the vibration component may be a motor 212 (shown in fig. 5) in the body 210 of the electric toothbrush, and the motor 212 may give a prompt to the user in a manner of stopping the motor 212 after responding to the alarm signal, or may give a prompt to the user in a manner of changing the vibration direction or other frequencies, which is not limited herein.

Thus, when the electric toothbrush 200 with the electric toothbrush head 100 is used for brushing teeth, if the brushing force is too large, the bristle part 20 can be prompted to move from the first position to the second position, and then the first trigger switch 30 is triggered, the first trigger switch 30 sends an alarm signal after being triggered, the alarm signal can be responded by the alarm part 40, and then an alarm prompt message is sent to remind a user that the brushing force is too large, and the user can reduce the brushing force under the prompt, so that the brushing cleaning efficiency is improved.

In addition, because the first trigger switch 30 is triggered by the movement of the bristle part 20, and the bristle part 20 is directly contacted with the teeth of the user, the tooth brushing force can be fed back in time, the reaction is quick, and no additional movement structure is needed, so the whole structure is simple.

Referring again to fig. 3, in some embodiments, the powered toothbrush head 100 further includes a first elastic element 50, wherein two ends of the first elastic element 50 respectively abut against the head body 10 and the bristle element 20 to provide a pre-load force for holding the bristle element 20 in the first position. Thus, the first trigger switch 30 can be triggered by the bristle part 20 resisting the elastic force of the first elastic part 50 under the action of the external force, and the toothbrush can automatically recover to the position separated from the first trigger switch 30 after the external force disappears, so that the tooth brushing force can be adjusted quickly, and the user experience is improved. Specifically, the first antenna elastic member 50 includes a spring, and in other embodiments, may also be elastic rubber or silicone, and is not limited herein.

Specifically, in the embodiment of the present application, the first elastic member 50 is disposed in the first accommodating chamber 11, and in other embodiments, may be disposed outside the first accommodating chamber 11, which is not limited herein.

In some embodiments, the head body 10 is provided with a first positioning member 12, and the first elastic member 50 is matched with the first positioning member 12 to be positioned on the head body 10. Specifically, the first positioning element 12 is a positioning protrusion or a positioning groove. In another embodiment, the bristle member 20 is provided with a second locating member 21, and the first resilient member 50 cooperates with the second locating member 21 to locate the bristle member 20. Specifically, the second positioning element 21 is a positioning protrusion or a positioning groove. In other embodiments, the brush head body 10 is provided with a first positioning member 12, the first elastic member 50 is matched with the first positioning member 12, the bristle member 20 is provided with a second positioning member 21, and the first elastic member 50 is matched with the second positioning member 21. The positioning means are provided to prevent the first elastic member 50 from being displaced during the movement of the bristle part 20, thereby stabilizing the movement of the bristle part 20.

Further, the bristle part 20 includes a bristle part body 22 and an elastic buckle 23, the elastic buckle 23 includes an elastic arm 231 and a buckle part 232, one end of the elastic arm 231 is connected with the bristle part body 22, the other end extends in a first direction far away from the bristle part body 22, the buckle part 232 protrudes from one side of the elastic arm 231 in a second direction, and the buckle part 232 can prop against the brush head body 10 under the action of the pre-tightening force of the first elastic part 50, so that the bristle part body 22 is limited on the brush head body 10, wherein the first direction is intersected with the second direction. Specifically, the first direction is the same as the direction of movement of the bristle set 20 relative to the head body 10, and the first direction is perpendicular to the second direction. Through the elastic buckle 23, in the process of installing the bristle part 20 to the installation opening, the buckling part 232 resists against the side wall of the brush head body 10 to enable the elastic arm 231 to generate elastic deformation, after the elastic arm reaches the installation position, the resistance disappears, the buckling part 232 can return under the action of the elastic arm 231, and then the buckling part 232 is abutted against the brush head body 10. The use of the resilient snap 23 allows for a more secure connection between the bristle part 20 and the head body 10.

In addition, it should be noted that the elastic buckle 23 is provided to make the bristle part 20 detachable with respect to the toothbrush head body 10, so that only the bristle part 20 needs to be replaced after the bristles are damaged or old, and the whole electric toothbrush head 100 does not need to be replaced, thereby saving the replacement cost. In other embodiments, the bristle member 20 may be detachable from the head body 10 by way of a non-elastic snap 23, such as a sliding detachment, and the like, without limitation.

Specifically, in the embodiment of the present application, the elastic arm 231 can extend into the first accommodating chamber 11, and the fastening portion 232 abuts against a chamber wall of the first accommodating chamber 11. In other embodiments, the elastic buckle 23 may be outside the first receiving cavity 11, and is not limited herein.

In particular, in the present embodiment, the bristle part 20 includes at least two resilient tabs 23, the at least two resilient tabs 23 being spaced circumferentially along the bristle part body 22. Preferably, the bristle set 20 includes three two resilient catches 23.

In some embodiments, the bristle members 20 are sealingly connected to the head body 10 by a sealant. Specifically, the sealant is filled into the first accommodation chamber 11. In other embodiments, the sealing members may be connected by other sealing structures, and are not limited herein.

In some embodiments, the powered toothbrush head 100 further comprises a second trigger switch 60, the second trigger switch 60 is disposed in the first cavity 11, the bristle part 20 further comprises a third position during movement relative to the head body 10, the third position is between the first position and the second position, the second trigger switch 60 is capable of being triggered when the bristle part 20 is in the third position, and the second trigger switch 60 is capable of sending a vibration frequency signal when triggered. Specifically, the vibration frequency signal sent by the second trigger switch 60 can be responded by the motor 212 in the power toothbrush body 210, thereby enabling the motor 212 to vibrate at the first vibration frequency. Thus, when the bristle set 20 contacts the user's teeth, the bristle set 20 moves to first activate the second trigger switch 60, thereby allowing the motor 212 to vibrate at the first vibration frequency to clean the teeth.

In the present embodiment, upon activation of the electric toothbrush 200, the motor 212 is capable of vibrating at a second vibration frequency, less than the first vibration frequency, to avoid excessive vibration causing toothpaste to fall from the bristle set 20 between brushings. Of course, in other embodiments, the motor 212 may be caused to vibrate at the first vibration frequency after the power toothbrush 200 is activated, or directly after the second trigger switch 60 is activated, so that the motor 212 is not operated until the bristle set 20 contacts the teeth, thereby preventing the toothpaste from falling out.

In some embodiments, powered toothbrush head 100 further includes a head circuit board 70 disposed within first receiving cavity 11, with first trigger switch 30 integrated into head circuit board 70. Likewise, the second trigger switch 60 may be integrated on the brushhead circuit board 70. In other embodiments, the warning member 40 may be integrated on the brushhead circuit board 70. Specifically, the brushhead circuit board 70 is connected to the wall of the first accommodating chamber 11 by screws.

As shown in fig. 4, in some embodiments, the electric toothbrush head 100 further includes a vibration transmission shaft 75, the vibration transmission shaft 75 can transmit the vibration generated by the motor 212, the vibration transmission shaft 75 is disposed on the toothbrush head body 10 and has one end electrically connected to the first trigger switch 30 and the other end for connecting to the main control board 213 of the electric toothbrush body 210 of the electric toothbrush 200. Thus, the first trigger switch 30 can be controlled by the main control board 213 of the electric toothbrush 200, and does not affect the function of replacing the brush head 100 of the electric toothbrush. It should be noted that since the first trigger switch 30 is connected to the main control board 213 through the vibration transmission shaft 75, the existing components of the electric toothbrush 200 themselves are utilized, and an additional electrical connection structure is not required, thereby simplifying the overall structure.

In addition, to improve the conductivity of the vibration transmission shaft 75, in some embodiments, the percentage of nickel element may be increased in the vibration transmission shaft 75.

Further, in order to prevent the vibration of the vibration transmission shaft 75 from affecting the first trigger switch 30, the electric toothbrush head 100 further includes a first electrical connection line 80 and an electrical connection block 82, one end of the first electrical connection line 80 is electrically connected to the first trigger switch 30, the other end of the first electrical connection line 80 is connected to the electrical connection block 82, and one end of the electrical connection block 82 away from the first electrical connection line 80 is in contact with the vibration transmission shaft 75. In this way, by providing the first electrical connection line 80, the vibration transmitted by the vibration transmission shaft 75 to the first trigger switch 30 can be weakened or even eliminated, and the connection between the first electrical connection line 80 and the vibration transmission shaft 75 can be made reliable by the electrical connection block 82, avoiding disconnection during vibration.

Further, the electric toothbrush head 100 further comprises a second elastic element 85, wherein the second elastic element 85 is compressed between the toothbrush head body 10 and the electrical connection block 82, and is used for providing a pre-tightening force for the electrical connection block 82 to abut against the vibration transmission shaft 75. In this manner, the electrical connection block 82 and the vibration transmission shaft 75 can be kept in contact at all times without affecting the electrical connection relationship therebetween by providing the second elastic member 85. Specifically, the second elastic member 85 includes a sponge, or other porous structure, and is not limited herein.

In some embodiments, the head body 10 includes a bristle holder 90, the bristle holder 90 being mounted in the second receiving chamber 15 for supporting the oscillating drive shaft 75. Specifically, a detent 751 or a detent projection 14 is provided on the bristle holder 90. Specifically, the bristle holder 90 is mounted in the second receiving cavity 15 by a snap or detent.

In some embodiments, the brush head support 90 has a third receiving chamber 91, both ends of the third receiving chamber 91 are respectively communicated with the second receiving chamber 15 and the outside, and the vibration transmission shaft 75 is disposed in the third receiving chamber 91.

Referring again to fig. 1, and based on the same inventive concept, the present application also provides a power toothbrush 200 including the above-described power toothbrush head 100 and a power toothbrush body 210 connected to the power toothbrush head 100. Specifically, powered toothbrush head 100 may be integrally disposed with or removably attached to powered toothbrush body 210.

As shown in fig. 5, further, the power toothbrush body 210 includes a body 211, and a motor 212 and a main control board 213 mounted on the body 211, the motor 212 is controlled to provide a vibration force to the power toothbrush head 100, and the first trigger switch 30 is connected to the main control board 213 in a communication manner. Thus, the first trigger switch 30 transmits an alarm signal to the main control board 213, and the alarm 40 and the motor 212 are controlled by the main control board 213. Similarly, the second trigger switch 60 is also communicatively connected to the main control board 213.

In some embodiments, the motor 212 includes a vibrating motor shaft 2121, and the first trigger switch 30 is electrically connected to the main control board 213 through the vibrating motor shaft 2121. Similarly, the second trigger switch 60 may be electrically connected to the main control board 213 through the vibration motor shaft 2121. Thus, the electric toothbrush body 210 itself is connected to the first trigger switch 30 in a communication manner without an additional electrical connection structure, thereby simplifying the overall structure.

Specifically, an end of the vibration transmission shaft 75 remote from the first trigger switch 60 is butted against an end of the vibration motor shaft 2121. In this way, the first trigger switch 60 can be electrically connected to the main control board 213 via the vibration transmission shaft 75 and the vibration motor shaft 2121.

Further, the electric toothbrush body 210 further includes an electric connection assembly, one end of which is attached to the vibrating motor shaft 2121 along the radial direction of the vibrating motor shaft 2121, and the other end of which is electrically connected to the driving plate 213. So, can avoid electric connection assembly to set up at the tip of vibrating motor shaft 2121 and influence its and the butt joint between the vibration transmission shaft 75, in addition, also be favorable to increasing laminating area, improve and connect the reliability.

Furthermore, the electrical connection assembly includes a conductive plate 214 and a second electrical connection line 215, the conductive plate 214 is attached to the vibrating motor shaft 2121, one end of the second electrical connection line 215 is connected to the conductive plate 214, and the other end is electrically connected to the active plate 213. Thus, the structure of the conducting strip 214 is simple, the attaching area of the conducting strip and the vibrating motor shaft 2121 is large, and the second electric connecting line 215 is arranged, so that the influence of the vibration generated by the vibrating motor shaft 2121 on the electric connection between the vibrating motor shaft and the active plate 213 can be reduced or even eliminated, and the connection reliability is improved. Specifically, the conductive plate 214 may be welded to the vibrating motor shaft 2121. Specifically, the conductive sheet 214 is a metal conductive sheet.

In some embodiments, in order to make the positioning of the conductive plate 214 with respect to the vibration motor shaft 2121 more stable, a stepped groove 2122 is provided on the outer side of the vibration motor shaft 2121, and the conductive plate 214 is attached to a bottom wall of the stepped groove 2122 extending in the axial direction.

In the embodiment of the present application, the electric toothbrush body 210 further includes a battery 216, the battery 216 is electrically connected to the main control board 213 and the motor 212, and the battery 216 can supply power to the motor 212.

In some embodiments, the body 211 further includes a body bracket 217, the body bracket 217 is installed in the third accommodating chamber 2111 of the body 211, and the motor 212 and the main control board 213 are both installed on the body bracket 217.

The electric toothbrush head 100 and the electric toothbrush 200 provided by the embodiment of the application have the following beneficial effects:

when the electric toothbrush 200 with the electric toothbrush head 100 is used for brushing teeth, if the brushing force is too large, the bristle part 20 is enabled to move from the first position to the second position, the first trigger switch 30 is triggered, the first trigger switch 30 sends an alarm signal after being triggered, the alarm signal can be responded by the alarm part 40, and then alarm prompt information is sent to remind a user that the brushing force is too large, the user can reduce the brushing force under the prompt, and the brushing cleaning efficiency is improved.

In addition, because the first trigger switch 30 is triggered by the movement of the bristle part 20, and the bristle part 20 is directly contacted with the teeth of the user, the tooth brushing force can be fed back in time, the reaction is quick, and no additional movement structure is needed, so the whole structure is simple.
