[0001] The utility model relates to the technical field of electric nursing products, in particular to a nursing appliance driving device and an electric toothbrush. Background Art

[0002] In order to comply with the EU's new regulations on replaceable batteries, existing electric toothbrushes, facial cleansers, massagers, etc. are gradually adopting nickel-metal hydride rechargeable batteries. Personal care products using nickel-metal hydride rechargeable batteries are prone to voltage drop during knocking or falling, causing the product to shut down. After power failure, the product needs to be placed on a charger for activation before it can be used, which causes trouble and is very unfriendly to consumers.

[0003] The above-mentioned defects of the prior art are mainly due to the fact that the currently commonly used direct welding method is difficult to adapt to the use of replaceable batteries, and needs to be restarted with a charger after power failure, which undoubtedly brings a lot of inconvenience to consumers.

[0022] First embodiment

[0023] Please refer to Figure 1 One embodiment of the utility model provides a nursing appliance driving device, including a working module 10, a battery 20, and a control circuit 30. The working module 10 is electrically connected to the control circuit 30. The battery 20 is provided with a wire 40 and a first connection terminal 50 connected in sequence. The control circuit 30 is provided with a second connection terminal 60. The first connection terminal 50 is used to be electrically connected to the second connection terminal 60, so that the battery 20 and the control circuit 30 are electrically connected through the wire 40.

[0024] Specifically, the first connection terminal 50 is a male connector, the second connection terminal 60 is a female connector, the second connection terminal 60 is fixedly connected to the control circuit 30, the first connection terminal 50 is fixed to the wire 40 and the battery 20, and is connected with the second connection terminal 60 after the battery 20 is replaced. Since the battery 20 and the control circuit 30 are electrically connected by the wire 40, when the nursing appliance falls to the ground, the flexibility of the wire 40 itself can buffer the impact force and reduce the possibility of disconnection at the connection. On the basis of the connection of the wire 40, the first connection terminal 50 and the second connection terminal 60 are further used to ensure the stability of the connection.

[0025] In this embodiment, the working module 10 includes a motor 11 and a transmission mechanism 12 . The control circuit 30 is connected to the motor 11 for controlling the working state of the motor 11 . The transmission mechanism 12 is connected to the motor 11 for adjusting the driving mode of the motor 11 .

[0026] Specifically, the control circuit 30 is mainly used to control the vibration or rotation mode of the motor 11, as well as the time, frequency, etc. of the vibration or rotation. The transmission mechanism 12 is used to adjust the driving mode of the motor 11, such as adjusting the rotating axis of the motor 11 from the vibration mode to the rotation mode, etc.

[0027] In this embodiment, the arrangement of the wires 40 forms at least one corner.

[0028] Specifically, the conductor 40 is preferably arranged in a straight line as far as possible. Since the length of a straight line is the shortest, this results in a lack of space for the conductor 40 to move flexibly, and a tight conductor 40 is not conducive to buffering impact force.

[0029] Furthermore, nursing appliances are usually small in size. In order to prevent the wire 40 from being too long and affecting the internal space, the present embodiment avoids the conventional "U"-shaped arrangement and instead partially forms an "L" shape, thereby ensuring the active length of the wire 40 and avoiding excessive space occupation.

[0030] The nursing appliance driving device provided in this embodiment electrically connects the battery 20 and the control circuit 30 by using a wire 40, a first connecting terminal 50 and a second connecting terminal 60. The wire 40 provides a certain flexibility for the connection between the two to prevent the battery 20 and the control circuit 30 inside from being slightly vibrated and causing instantaneous voltage reduction and power failure when the nursing appliance falls to the ground or collides. The coordinated connection of the first connecting terminal 50 and the second connecting terminal 60 can ensure the connection strength of the wire 40 and avoid unstable connection with the control circuit 30. At the same time, the coordination of the first connecting terminal 50 and the second connecting terminal 60 is also conducive to the rapid replacement of the battery 20, eliminating the disadvantages of welding electrical connection.

[0031] Second embodiment

[0032] Please refer to Figure 2 The utility model also provides an electric toothbrush, including a brush head 110, a shell 120 and a care tool driving device as described in the first embodiment, the care tool driving device is arranged in the shell 120, the brush head 110 is fixed to the shell 120, and the working module 10 is electrically connected to the brush head.

[0033] In this embodiment, the housing 120 is provided with an escape opening for allowing the battery 20 to be inserted into or removed from the housing 120 , and also has a protective cover for closing or exposing the escape opening.

[0034] In this embodiment, the working module 10 is connected to the brush head 110 via a transmission shaft 130 .

[0035] Specifically, after the working mode is adjusted by the circuit board 30 , the working module 10 transmits kinetic energy to the brush head 110 through the transmission shaft 130 , so that the brush head 110 directly performs the preset function in the oral cavity.

[0036] In this embodiment, the electric toothbrush further includes a fixing bracket 140 for fixing the care tool driving device in the housing 120 . The fixing bracket 140 has a notch 141 . The notch 141 is used to avoid the transmission shaft 130 extending from the working module 10 to the brush head 110 .

[0037] Specifically, the fixing bracket 140 fixes the working module 10 , the battery 20 , the control circuit 30 and the wire 40 in the care appliance driving device together in the housing 120 , and opens a notch 141 to facilitate the transmission of the brush head 110 and the working module 10 .

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
