Description

Technical Field

[0001] The present disclosure relates to a personal hygiene device, and more particularly to an oral care device. Background Art

[0002] Some oral care devices combine the functions of an electric toothbrush and an electric water flosser. The motor rotates and vibrates at high speed, causing the brush head to vibrate at a high frequency, or the punch head to output a high-pressure water jet to deeply clean the teeth and gaps between teeth. This can more effectively remove dental plaque and reduce oral diseases such as gingivitis, periodontal disease, and bleeding gums. The vibration of the brush head and the output of pulsed water flow are usually powered by different power components, both of which require electrical energy. Some oral care devices include a main unit and a handle, with different power components respectively arranged in the main unit and the handle. For such products, how to provide electrical energy to the power components and improve the product's endurance is a technical problem that needs to be solved urgently in this field.

The handle 1 and the host 2 can be fixedly connected, and the host 2 continuously provides a water source for the handle 1. Preferably, the handle 1 is detachably connected to the host 2 via a fluid connection assembly, which is detachably arranged at the second end of the handle 1 or adjacent to the second end of the handle 1, and the fluid connection assembly and the handle 1 have two connection states: installation and separation. When the fluid connection assembly is installed on the handle 1, the liquid in the fluid reservoir 2.11 is transported to the handle through the fluid connection assembly, and the user can choose to brush teeth or rinse teeth; when the fluid connection assembly and the handle 1 are separated from each other, the water path between the two is disconnected, and the handle 1 can no longer be used for rinsing teeth, and the handle 1 can be used as a toothbrush. The oral care device provided in this embodiment can realize the functions of both a toothbrush and a rinsing device, thereby improving the cleaning effect on the oral cavity.

[0050] The oral care device also includes a wireless charging module 3, which is used to transmit the power of the host 2 to the handle 1. Specifically, the wireless charging module includes a wireless charging transmitting coil 2.2 provided on the host 2 and a wireless charging receiving coil 1.3 provided on the handle 1. The handle power supply 1.7 is electrically connected to the wireless charging receiving coil 1.3 to receive the energy transmitted from the host 2. The handle 1 is charged through the host 2 without setting an additional charging structure. At the same time, the host 2 is suitable for being placed on a table, and the handle 1 can be attached to the host 2 to achieve charging. The handle 1 is used for users to hold to clean the oral cavity. It is usually slender and easy for users to hold. The volume is small, and the battery capacity in the handle 1 is relatively small. The host 2 includes a fluid reservoir 2.11, which is usually placed on the table when in use and does not need to be held.

It should be noted that after receiving the power control signal, the second power assembly can control the water pressure, flow rate and / or flow rate of the fluid stored in the fluid reservoir flowing out of the second power assembly, so that the fluid flows out of the fluid outlet with different impact intensities. Generally, the pressure of the fluid is proportional to the current working gear of the oral care device. For example, the greater the current working gear, the greater the pressure of the fluid, and the greater the impact strength when the fluid flows out.

[0052] The host 2 is the core control component of the oral care device, which is equipped with a host power supply and a fluid system. The host power supply includes but is not limited to: a host battery and / or a host external power supply circuit, and the fluid system includes a fluid reservoir and a pump connected to the fluid reservoir.
