Description

Technical Field

[0001] This utility model relates to the field of cold flame spraying machine technology, and in particular to a spraying system for an upward spraying cold flame spraying machine. Background Technology

[0002] Currently, cold flame sprayers are widely used in celebrations, performances, and other occasions to create a lively atmosphere. Upward-spraying cold flame sprayers, due to their upward spray direction and more prominent visual effect, are increasingly being used. Traditionally, these sprayers typically employ a simple structural design: a vertical nozzle with a fan connected to its lower end. During spraying, the cold flame mixture is fed into the nozzle through an inlet on the side wall, and the rising airflow generated by the fan propels the mixture upward, creating a dazzling cold flame effect.

[0003] However, this conventional top-spraying cold flame sprayer has its drawbacks. Due to gravity, some of the cold flame powder inevitably settles downwards. Since the blower is located below the nozzle, this settled powder easily falls into the blower's interior, leading to a series of problems. For example, powder adheres to the motor, affecting its normal operation and even causing damage; powder accumulates on the blower impeller, increasing the impeller's load, reducing the blower's efficiency, and in severe cases, even jamming the impeller, causing the blower to stop and rendering the sprayer unable to function properly.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

The lower part of the side wall of the spray pipe 1 is provided with a cold flame input interface 12 for feeding cold flame powder and compressed air into the interior of the spray pipe.

[0022] The lower end of the spray pipe 1 is not directly connected with the fan, but is connected with a curved bend pipe 2. The tail end of the bend pipe 2 is upwardly curved to form a lifting angle A, and the fan 3 is connected to the bend pipe 2. Fig. 3 The utility model discloses a spray system of upper spray type cold flame spray painting machine, aims at solving the problem of the cold flame powder falling into the fan to cause the failure in the prior art, and improves the spray painting effect.

The tail end of the bend pipe 2 is preferably designed as a tapered opening 21 which gradually narrows from the outside to the inside, and the fan 3 is installed at the outer end of the tapered opening 21, so that the airflow can be better guided and the fan efficiency can be improved.
