Gear transmission in the structure of tooth punch

As a new type of oral cleaning appliance, the dental flusher is widely used. In Europe and the United States, the dental flusher is a must-have hygiene product for many families. Nowadays, the dental flusher has entered China, and many people have gradually liked this comfortable and effective dental and oral hygiene products. Its effect on periodontal health care, treatment of gingivitis, correction of deformities, and restoration of dental crowns has been proven in various tests. In developed countries, dental flushers have entered the market as early as forty years ago and have become essential daily necessities for people's families.

The tooth flusher drives the eccentric cam on the face gear through the motor, and then the eccentric cam drives the pump body to pressurize the water, which can generate ultra-fine high-pressure pulsed water jets. The nozzles can make this high-pressure pulsed water jets flush to the mouth without any obstacles. Areas, including toothbrushes, dental floss, toothpicks between the teeth and deep gums that are not easily reachable. It can effectively clean the plaque on the tooth surface, keep the mouth clean, and make people feel fresh. Clean the tongue coating to remove bad mouth odors. Powerful removal of food residues and harmful bacteria accumulated in the gaps between teeth that cannot be reached by toothbrushes and dental floss, effectively preventing tooth decay, gingivitis, dental calculus and periodontitis. Massage and stimulate the gums, improve blood circulation, relieve toothache, and inhibit gum bleeding.

The motor of the tooth punch is rotating. How to realize the linear movement of the piston rod of the pump body? It is realized by the structure of motor teeth and face gears (also called crown teeth). There are two structures of motor teeth and face gears (crown teeth).

1. The motor teeth are straight teeth, and the face teeth are also straight teeth (the tooth profile is involute). The advantages are: simple structure, simple processing, relatively low mold cost, but the disadvantage is that the noise is relatively large and the torque is relatively small.

2. The motor teeth are conical arc gears, and the face teeth are arc gears. The advantage is: low noise, because this tooth profile has a high meshing degree, so the torque is relatively large. The disadvantage is that the cost of the mold is relatively high.

   As consumers have higher and higher requirements for products, manufacturers of dental appliances are also inclined to the second transmission scheme.
