Domestic pulsed toothwash machine

Abstract

The invention discloses a domestic pulsed toothwash machine. According to the domestic pulsed toothwash machine, a water pump motor is a 12V direct-current motor, a micro-motor with a working current of 1A provides power for a water pump body, a water inlet in the water pump body is communicated with a water tank, and a water outlet of the water pump body is communicated with a handle nozzle through a hose; the water pump body is provided with a modularized pump body; the water pump motor is connected with a worm-worm gear speed reduction device, an eccentric gear is directly driven to drive a piston body to carry out the pulsed circulation working of the water pump, a water flow with a pulse of 1200 times / min and a weight of 0.8KG can be generated for cleaning dirt and residues on gap and roots of teeth. The domestic pulsed toothwash machine has a fast cleaning effect on dental plaque and has an assistant curative effect on patients with periodontitis to a certain extent.

Description

technical field [0001] The invention relates to a cleaning appliance for cleaning teeth, in particular to a household pulse tooth cleaning machine. Background technique [0002] The imported and domestic scalers or rinsers currently on the market use a 220V AC shaded pole motor to drive a positive displacement pump and a plunger pump, which are connected to a water tank for water discharge, and the outlet water is connected to a combination of a soft spring tube and a handle. The spray gun that becomes, tooth is cleaned, finds following deficiency in actual use: 1, the 220V alternating current voltage that adopts, because tooth washing machine is generally used in toilet, has water, just has certain potential safety hazard. If the water pump works and causes blockage, the motor will be stopped, causing the motor to burn out, which will cause serious consequences of short circuit. 2. The pump body and piston materials of the water pump are generally made of plastic integral ...

AI Technical Summary

Problems solved by technology

[0002] The imported and domestic scalers or rinsers currently on the market use a 220V AC shaded pole motor to drive a positive displacement pump and a plunger pump, which are connected to a water tank for water discharge, and the outlet water is connected to a combination of a soft spring tube and a handle. The finished spray gun cleans the teeth, and finds the following deficiencies in actual use: 1. The 220V AC voltage used, because the toothwashing machine is generally used in the bathroom, there will be water, and there is a certain potential safety hazard

If the water pump works and causes blockage, the motor will be stopped, causing the motor to burn out, which will cause serious consequences of short circuit

2. The pump body and piston materials of the water pump are generally made of plastic integral die-casting. Due to the plastic properties, its shrinkage varies greatly under different temperature environments, resulting in the coordination coefficient between the piston and the pump body of the water pump. Therefore, there may be changes in water flow and pressure, which may cause water leakage in the pump

3. The shaded pole motor is used to drive the small plastic gear to drive the reduction ratio of the large plastic gear, and to drive the eccentric wheel to drive the piston to perform the circulating work of the water pump. Because it is a spur gear, it will produce a lot of noise during work; the small gear drives the large gear to reduce Torque is reduced to reduce the working efficiency of the water pump, so in order to achieve the working torque of the water pump, only 220V, 25W or more shaded pole motors can be used

4. The soft spring tube is not easy to retract after the handle is pulled out, taking up space
