Soft projectile launcher

Abstract

A soft projectile launcher includes a launching tube including a power channel, a projectile loading channel, and a projectile exit channel connected in sequence, a projectile entry tube including a projectile entry channel connected to the projectile loading channel and configured to provide a soft projectile to the projectile loading channel, and a power assembly connected to a free end of the power channel and configured to provide power for launching the soft projectile. At least a part of at least one of the projectile entry channel, the projectile loading channel, or the projectile exit channel includes an elliptical channel.

What is claimed is: 
     
         1 . A soft projectile launcher comprising:
 a launching tube including a power channel, a projectile loading channel, and a projectile exit channel connected in sequence;   a projectile entry tube including a projectile entry channel connected to the projectile loading channel and configured to provide a soft projectile to the projectile loading channel; and   a power assembly connected to a free end of the power channel and configured to provide power for launching the soft projectile;   wherein at least a part of at least one of the projectile entry channel, the projectile loading channel, or the projectile exit channel includes an elliptical channel.   
     
     
         2 . The soft projectile launcher of  claim 1 , wherein:
 the power assembly includes a compression chamber and a compression piston;   the compression piston is configured to move along an inside of the compression chamber, and airtightly and slidably fitted with an inner wall of the compression chamber; and   one end of the compression chamber corresponding to the compression piston is airtightly connected to the power channel.   
     
     
         3 . The soft projectile launcher of  claim 2 , wherein:
 the power assembly further includes an extension tube including an extension channel, one end of the extension channel being airtightly connected to the compression chamber, and another end of the extension channel being in airtight connection with the power channel; and   a nozzle of the extension channel is configured to closely contact the soft projectile in the projectile loading channel.   
     
     
         4 . The soft projectile launcher of  claim 3 , wherein an intake clearance is provided at an edge of the nozzle of the extension channel. 
     
     
         5 . The soft projectile launcher of  claim 1 , further comprising:
 a projectile loading mechanism including a refill and a dial;   wherein:
 the dial is rotatably mounted at a bottom of the refill; 
 a projectile moving gap is provided at one side of the dial; 
 a projectile inlet is provided at a position at the bottom of the refill that corresponds to the projectile moving gap, the projectile inlet being connected with a free end of the projectile entry channel. 
   
     
     
         6 . The soft projectile launcher of  claim 5 , wherein a wall surface of the projectile moving gap is inclined. 
     
     
         7 . The soft projectile launcher of  claim 1 , wherein the projectile loading channel and the projectile exit channel are arranged coaxially or in a smooth curve. 
     
     
         8 . The soft projectile launcher of  claim 7 , wherein:
 the projectile loading channel and the projectile exit channel are arranged coaxially in a straight line; and   the projectile entry channel and the projectile loading channel are arranged perpendicular to each other.   
     
     
         9 . The soft projectile launcher of  claim 1 , wherein the projectile exit channel includes:
 a first projectile exit channel connected with the projectile loading channel; and   a second projectile exit channel airtightly connected to the first projectile exit channel airtightly connected via nested tubes.   
     
     
         10 . The soft projectile launcher of  claim 9 , wherein:
 the first projectile exit channel has an elliptical shape; and   a shape and a size of the second projectile exit channel are same as a shape and a size of the first projectile exit channel.
