The present application relates to the technical field of water pumps, and in particular to a water pump and an oral irrigator.
An oral irrigator is a structure configured to care for the oral cavity. The oral irrigator uses a certain pressure to spray the cleaning water column from the nozzle of the oral irrigator to clean the user's oral cavity. The oral irrigators are currently widely used in people's daily lives.
The Chinese Patent Publication No. CN217525450U discloses an oral irrigator, which includes: an oral irrigator housing, an oral irrigator upper cover and a nozzle. The oral irrigator housing is slidingly connected with a water tank. The interior of the oral irrigator housing is provided with a water pump structure for spraying the water in the water tank from the nozzle. The water pump structure includes a first machine core frame and a second machine core frame that are detachably connected. A battery is installed on one side of the first machine core frame. One side of the second movement frame is provided with a control assembly for controlling the working status of the oral irrigator. The first machine core frame and the second machine core frame are provided with motors. One end of the motor is provided with a driving wheel, and the driving wheel is meshed with a driven wheel. Both the driving wheel and the driven wheel are spiral bevel gears. The driven wheel is connected with a water pump assembly. The oral irrigator housing is provided with a locking assembly for locking and installing the nozzle. The second machine core frame is provided with a shock-absorbing assembly for shock-absorbing the water pump structure. However, the driven wheel is designed as a large plastic gear, after long-term use of the oral irrigator, the gear between the driving wheel and the driven wheel will be greatly worn, and the noise produced is also loud. Using this transmission method will cause great wear and tear on the sealing ring in the water pump, thus reducing the service life of the oral irrigator.

It should be noted that the driving member 3 drives the driving wheel to rotate and drives the first transmission gear 7, the second transmission gear 8 and the third transmission gear 9 to rotate, causing the driven gear 6 to start rotating, and then driving the first rotating wheel 22 to rotate, so that the driven member 24 drives the second transmission frame 23 and the third transmission frame 25 to perform linear movement. Since the second transmission frame 23 and the connecting rod 13 are fixedly connected by screws, the connecting rod 13 is driven to perform linear motion. Since the head and tail of the first moving groove 21 are closed, the piston 12 is driven to perform reciprocating linear movement, allowing the water pump to pump water or deliver water.
