application example 1

[0100] In application example 1, a piston driving assembly for an oral care device is provided, including a first gear 111, a connecting shaft 120, a second gear 130, a balance part 170, a transmission part 140 and a piston, the piston is a liquid part of the pump. The first gear 111 meshes with the second gear 130, the second gear 130 is rotatably fitted on the connecting shaft 120, and the first gear 111 has a first rotation axis, the second The gear 130 has a second axis of rotation, the first axis of rotation and the second axis of rotation being arranged at right angles. The balance member 170 is fitted to the second gear 130 , the transmission member 140 is eccentrically connected to the second gear 130 , and the piston is connected to the transmission member 140 .

[0101] When the first gear 111 rotates, the second gear 130 is driven to rotate, and drives the transmission member 140 and the piston to reciprocate. And taking the axis of the second gear 130 as a fulcru...

application example 2

[0103] In the second application example, a piston driving assembly for an oral care device is provided, which is different from the first application example in that the balance member 170 is specifically two pressing members 171 , and the two pressing members 171 It is matched with the first gear 111 at the first end 131 of the second gear 130, and forms three matching positions with the first end 131, and the three matching positions can determine a plane to ensure the first The first end 131 of the second gear 130 is located in a desired plane, so that the second gear 130 is not easily inclined.

application example 3

[0105] In Application Example 3, a piston driving assembly for an oral care device is provided, which is different from Application Example 1 in that the balance member 170 is specifically a support member 172 , and the second gear 130 has an opposite first gear 130 . One end 131 and a second end 132, the first gear 111 is engaged with the first end 131, the support 172 is supported on the second end 132, and the support 172 and the second gear A rolling fit is formed between 130 . The support 172 makes the second end 132 of the second gear 130 lie in a desired plane, so that the second gear 130 is not easily inclined. At the same time, the way of rolling fit makes the friction between the two less.

Abstract

The invention provides a piston driving assembly for an oral care device and the oral care device. The piston driving assembly comprises a first gear, a connecting shaft, a second gear, a balance component, a transmission component and a piston. According to the piston driving assembly for the oral cavity nursing device and the oral cavity nursing device, the axis of the second gear serves as a fulcrum, the first gear and the balance component apply torque in the opposite direction to the second gear, so that the second gear is stressed in a balanced mode, and the torque is balanced; and the situation that the second gear is abraded quickly due to uneven stress is avoided. Meanwhile, deflection of the second gear is avoided, abrasion between the second gear and the connecting shaft is avoided, the transmission efficiency and stability of the whole mechanism are prevented from being affected, and noise caused by unstable transmission is correspondingly reduced.

Description

technical field [0001] The present application relates to the technical field of oral care equipment, and in particular, to a piston driving assembly for an oral care device and an oral care device. Background technique [0002] The piston pump assembly is the core component of oral care devices such as dental irrigators. In the existing oral care devices, the piston pump assembly includes a piston cylinder and a piston fitted in the piston cylinder, and the piston is usually driven by a gear transmission structure. , the teeth of the driving motor mesh with the transmission teeth of the gear transmission structure to reduce the speed and increase the torque. At the same time, the rocker eccentrically arranged on the transmission teeth converts the rotary motion into the linear motion of the piston, so as to change the pressure in the piston cylinder and realize the fluid pressure. drive. During this process, the transmission teeth are subjected to uneven force, which is pr...
