Problems solved by technology

However, both driving methods will inevitably generate vibration and noise. In general, the higher the brushing intensity is selected, the more obvious the vibration and noise of the electric toothbrush will be, resulting in a poor user experience.

Embodiment 1

[0033] Electric toothbrush RMT with multiple resonant motors, such as figure 1 As shown, it includes: housing EH, controller CS, battery EB, resonant motor RM, equivalent crankshaft device EC, transmission device TM, and execution device ED.

[0034] In the attached picture, Indicates electrical connections, and / or signal connections, Indicates mechanical connections, and / or hydraulic piping connections.

[0035] The controller CS, the resonance motor RM, the equivalent crank device EC, and the battery EB are disposed in the housing EH. The execution device ED is arranged outside the housing EH, and the execution device ED is connected to the housing EH. The housing EH is configured at least as a base, and / or a mounting piece, and / or a connecting piece, and / or a supporting piece, and / or a fixing piece, and / or or peripheral envelopes. The resonance motor RM is the power source of the electric toothbrush RMT having a plurality of resonance motors. The resonant motor RM ...

Embodiment 2

[0052] Electric toothbrush RMT with multiple resonant motors, such as figure 2 As shown, its structure is similar to that of Embodiment 1, the difference is that in Embodiment 2, the motor bracket FB and the vibration damping device DP are added; the vibration damping device DP has the ability to reduce the vibration and noise transmitted by itself. function; the resonant motor RM and the equivalent crankshaft device EC are installed on the motor bracket FB; the motor bracket FB is connected to the housing EH through the vibration damping device DP; and / or The vibration damping device DP can absorb the vibration of the motor bracket FB by using its own spring vibrator system; EC transmits the vibration and / or noise function to the housing EH.

Embodiment 3

[0054] Electric toothbrush RMT with multiple resonant motors, such as image 3 As shown, its structure is similar to that of Embodiment 2, except that: in Embodiment 3, the vibration damping device DP is removed; the resonant motor RM includes a first resonant motor RM1 and a second resonant motor RM2; The first resonant motor RM1, the second resonant motor RM2 and the equivalent crankshaft device EC are all mounted on the motor bracket FB; the second resonant motor RM2 is connected to the said equivalent crankshaft device EC The first resonance motor RM1 is connected; the vibration phase of the second resonance motor RM2 is opposite to that of the first resonance motor RM1, and the equivalent crankshaft device EC transmits the vibration of the second resonance motor RM2 to the first The resonance motor RM1; the equivalent crankshaft device EC, the first resonance motor RM1 and the second resonance motor RM2 are all installed on the motor bracket FB; the equivalent crankshaft ...

Abstract

The invention provides at least one electric toothbrush (RMT) with multiple resonance motors, and particularly relates to an electric toothbrush (RMT) with multiple resonance motors, which is at least used for cleaning and nursing teeth and / or slits between the teeth and / or the oral cavity. The electric toothbrush at least comprises a shell (EH), an Execution Device (ED), a Resonance Motor (RM), and / or an equivalent crankshaft device (EC), and / or a transmission device (TM), and / or a Controller (CS), and / or a battery (EB), and / or a detection device, and / or a vibration damping Device (DP), wherein the shell (EH) is directly or indirectly combined and connected with the modules or devices, so that the functions of cleaning and nursing the teeth can be realized. Compared with the prior art, the electric toothbrush has the advantages that the equivalent crankshaft device (EC) is connected with each resonance motor and drives the electric toothbrush, so that the vibration of each resonance motor can be mutually counteracted, and the electric toothbrush is small in hand feeling vibration and good in use experience.

Description

technical field [0001] The present invention relates to at least one electric toothbrush with a plurality of resonant motors, especially an electric toothbrush with a plurality of resonant motors at least for cleaning and nursing teeth, and / or interdental space, and / or oral cavity. Background technique [0002] Electric toothbrush products are becoming more and more common in people's lives at present. Some of the current electric toothbrush products use a rotating motor to drive the vibration of the brush head through a series of transmission mechanisms, and some use a rotating vibration motor to drive the vibration of the brush head through a series of transmission mechanisms, thereby achieving the tooth cleaning effect. However, both driving methods will inevitably generate vibration and noise. In general, the higher the brushing intensity is selected, the more obvious the vibration and noise of the electric toothbrush will be, resulting in a poor user experience. [000...
