Description
CROSS REFERENCE OF RELATED APPLICATION

This application claims priority under 35 U.S.C. 119(a-d) to CN201720191673.9, filed Feb. 28, 2017 and CN201710531402.8, filed Jul. 3, 2017.


BACKGROUND OF THE PRESENT INVENTION

Description of Related Arts

More and more people feed cats or dogs in the house in China and in European and American countries. With the development of the society, people are crowded in the city and the private area for each people is further reduced, so the space for pet is limited. Favorite pet toys which are able to draw the attention of the pets appear in the market. A lot of research is carried out in the pet toy field and simple pet toys are no longer able to meet the needs of people. A series of pet toys which are able to improve the intelligence of the pets while playing are being developed by people to integrate the playing with the intelligence cultivation of the pets, such as an automatic tennis ball launcher for pets


While the pet dog plays with the automatic ball launcher, because the dog fetches the ball in the mouth, the ball tends to be contaminated by the saliva and dust. The ball is frequently stuck in the ball aisle and the launch distance is reduced. The ball is easily stuck in the aisle if the ball is contaminated by saliva and is wet, which is unpleasant during the playing between the owner and the pet.


Conventionally, the ball launch wheels of the automatic ball launcher for pets are cylinders with flat teeth. Although gears are set around the ball launch wheels, the contact surface of the wheel and the ball is small and the ball is easily slipping away or stuck in the launcher due to the abrasion or contamination of the wheel face by the saliva.


Chinese application 201380022590.1 (PCT/US2013/029124) publics a pet exercise and entertainment devices which comprises a launch funnel for launching projectiles for a pet to retrieve. The launch funnel has a feeder and a chute. The feeder is configured to receive a projectile and transport the projectile to an intake end of the chute. A sensor is configured to sense the projectile in the intake end of the chute and to command one or more motors to power up in response to sensing the projectile. An actuator is configured to release the projectile from the intake end of the chute into the launch end of the chute after a pre-determined time has elapsed. One or more wheels, rotated by the one or more motors, are configured to launch the projectile from the launch end of the chute. The contact surface of the wheels and the ball is small. The abrasion of the surface due to long time use and the saliva on the ball cause the ball slipping away or being stuck in the launcher, which is not enjoyable.
