Wind power generated by the blower is blown to the interior and exterior of the cloth sleeve through the air pipe and the air outlet separately, so that the bubble water exudes from a surface of the cloth sleeve to form bubbles, and the wind power is used to blow the bubbles to fly away, so as to form artificial snowflakes.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a bubble-type snowflake maker, and more particularly to an improvement of a bubble-type snowflake maker that uses wind power for blowing.
2. Description of the Related Art
A scenario such as drama and stage is used as an example, and the scenario uses, when necessary, a bubble-type snowflake maker to produce flying artificial snowflakes in the background, so as to improve dramatic and stage effects.
Currently, components such as a blower and a pump are provided in a machine body of a bubble-type snowflake maker, so as to use the pump to feed bubble water, and then use the blower to blow, by using wind power, bubbles to fly away from an outlet to form artificial snowflakes, thereby making a scenario of flying artificial snowflakes.
However, in a practical operation of a conventional bubble-type snowflake maker, when a blower uses wind power to blow bubbles to fly away from an outlet to form artificial snowflakes, the bubbles spread out from the outlet by a large angle, thus relatively reducing blowing distances of the bubbles; and most of the bubbles move along an outer peripheral surface of the outlet and drop, thus causing a slippery floor of a site and reducing a bubble-type snowflake effect. Therefore, how to solve the aforementioned problems is the subject that needs to be studied by persons skilled in the art.
SUMMARY OF THE INVENTION
A main objective of the present invention is that: a bubble-type snowflake maker uses an inner annular toothed edge and inner sharp teeth of a spray pipe to enable bubbles to be sent out in a centralized manner along a middle part of a pipe, so as to increase blowing distances of the bubbles and improve a snowflake effect, and prevent most bubbles from moving along an outer peripheral surface of the spray pipe and dropping, thereby avoiding a slippery floor of a stage site.
To achieve the objective disclosed above, in the improvement of a bubble-type snowflake maker of the present invention, the interior of a machine body of a main machine is provided with accommodating space for disposing a blower including a motor and a fan, so as to enable the to blower to send out wind power towards an air outlet pipe and an air outlet surrounding an outer periphery of the air outlet pipe, and for disposing a pump connected to a bubble water pipe, a tail end of which is connected to a bubble head, so as to enable the pump to outwardly transport bubble water to the bubble head along the flexible bubble water pipe; a tail end of the air outlet pipe is sleeved with a cloth sleeve extending outwardly, and the bubble head of the bubble water pipe is disposed in the air outlet pipe; the air outlet is outwardly connected to a spray pipe having an inner pipe, and the air outlet pipe and the cloth sleeve extend into the pipe; the inner diameter of the inner pipe of the spray pipe is greater than the outer diameter of the air outlet pipe; and an inner annular toothed edge radially extends inwardly along a tail end of the inner pipe of the spray pipe. In the aforementioned improvement of a bubble-type snowflake maker, the blower is provided with a housing for accommodating the motor and the fan; an external side of the housing is connected to the air outlet pipe and the air outlet; and a plurality of annularly arranged and spaced air outlet holes are provided on the housing and between the air outlet pipe and the air outlet, so as to be in communication with the inner pipe of the spray pipe. In the aforementioned improvement of a bubble-type snowflake maker, the inner annular toothed edge of the spray pipe has a plurality of annularly arranged and connected inner sharp teeth.
In the aforementioned improvement of a bubble-type snowflake maker, the pump is disposed in the machine body of the main machine; and two opposite radial holes are separately disposed at outer peripheries of the spray pipe and the air outlet pipe, so that a tail end of the bubble water pipe enters the air outlet pipe through the two radial holes, so as to be connected to the bubble head.
