Description

Technical Field

[0001] The utility model belongs to the technical field of water flossing equipment, and in particular relates to a water pump for a water flosser and a water flosser. Background Art

[0002] An oral irrigator is a tool that uses pulsed water flow to clean teeth and between teeth. It is an oral hygiene auxiliary tool. Traditional oral irrigators use an AC 220V fixed speed motor to drive a water pump to produce a constant pulse water flow. The pulse rate is fixed at around 1200 times / minute. However, due to the high heat generated by the AC motor, it is generally recommended not to use it for more than 2 minutes at a time, and not to use it for more than 5 minutes within every 2 hours, to avoid overheating of the machine and causing malfunctions.

[0003] For example, patent application No. 202221096537.9 discloses a water pump for a water flosser, which includes: a water pump lower cover, which is connected to the water pump upper cover by a side buckle, a first self-tapping screw is installed through the water pump lower cover and the water pump upper cover, a motor is fixed to one end of the inner side of the water pump lower cover, and a bevel gear is fixed to the end of the output shaft of the motor; a bevel gear, which is meshed and connected with the bottom end of the bevel gear, a gear shaft is installed through the middle of the bevel gear, and the bottom and top ends of the gear shaft are respectively connected to the holes opened on the inner walls of the water pump lower cover and the water pump upper cover, and the bevel gear The top is connected to one end of the piston connecting rod assembly, and the other end of the piston connecting rod assembly is connected to the pump chamber, and the pump chamber is installed on the other end of the water pump lower cover and the water pump upper cover through the second self-tapping screw; the nozzle sealing sleeve, the nozzle sealing sleeve is installed at the end of the pump chamber, the inner side of the nozzle sealing sleeve is fitted with one end of the water outlet valve plate bracket, the other end of the water outlet valve plate bracket is fitted with the inner water outlet valve plate, and the inner water outlet valve plate is installed at the inner end of the pump chamber, and the inner sleeve of the water outlet valve plate bracket is provided with a spring, and the end of the spring is fitted with the end of the pump chamber, and the bottom of the pump chamber is installed with a water pump water inlet joint through the third self-tapping screw. The internal structures of the water pump of the water irrigator cooperate with each other, which is more stable and has low noise and vibration. However, whether it is the water pump of the water irrigator or the water pump of the water irrigator in the prior art, the piston inside it cannot be heated and dried. After each use, a certain amount of water and water vapor will remain inside the piston without being discharged, and thus remain inside the piston. After a period of non-use, it is easy to mold and breed bacteria. When it is used later, it is unhygienic and not conducive to oral health. Utility Model Content

[0037] The heating element 19 can also be a structure such as a coil. The utility model can use a high-frequency, high-voltage current that changes rapidly to flow through the coil to generate a high-speed changing alternating magnetic field. When a ferrous metal body is inside (that is, the steel sleeve is on the inside of the coil), the eddy current causes the steel sleeve to heat up, thereby increasing the temperature of the piston 14 and other parts inside the steel sleeve, thereby achieving the purpose of quickly volatilizing the internal water or water vapor. After each use of the utility model, the heating element 19 is automatically started to electrically heat the piston 14 and other parts, quickly volatilizing the water or water vapor inside the piston 14, and then using the movement of the piston 14 of the utility model itself, the water vapor in the piston 14 is forced to be discharged to the outside of the piston 14, and the cavity of the piston 14 sleeve 2 is actively dried, thereby protecting the oral health of the user.
