Description

Technical Field

[0001] The invention relates to the technical field of cold flame spray machines, in particular to a spraying system of an upward spraying type cold flame spray machine. Background Art

[0002] At present, cold flame sprayers are widely used in celebrations, performances and other occasions to create a warm atmosphere. The upward spray cold flame sprayer has a more prominent visual effect due to its upward spray direction, and its application is increasing day by day. Traditional sprayers of this type usually adopt a simple structural design: a vertical nozzle with a fan connected to its lower end. When spraying, the cold flame mixture is sent into the nozzle through the inlet on the side wall of the nozzle, and the rising airflow generated by the fan sprays the mixture upward, forming a gorgeous cold flame effect.

[0003] However, this conventional upward spraying cold flame spray machine has defects. Due to the effect of gravity, part of the cold flame powder will inevitably settle downward. Since the fan is located below the nozzle, these settled powders are very likely to fall into the fan, causing a series of problems, such as: powder adheres to the motor, affecting the normal operation of the motor, and even causing damage to the motor; powder accumulates on the fan impeller, increasing the load of the impeller, reducing the efficiency of the fan, and in severe cases, even jamming the impeller, causing the fan to stop, making the spray machine unable to work normally.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these shortcomings, and the present invention is made based on this situation. Summary of the invention

[0005] The object of the present invention is to overcome the deficiencies of the prior art and to provide a spraying system for an upward spraying cold flame spraying machine which can improve the reliability and service life of the spraying machine.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The spraying system of the upward-spraying cold flame sprayer of the present invention prevents cold flame powder from falling into the fan by connecting the lower end of the nozzle to an upwardly tilted curved pipe and then to a fan; increases the spraying height by arranging a wind gathering section at the lower part of the nozzle; and converts vortex wind into direct current wind to enhance the spraying effect by arranging a stator at the connection between the nozzle and the curved pipe, thereby finally achieving the purpose of preventing fan failure, enhancing spraying performance and enhancing the spraying effect, and has the advantages of simple structure, high reliability and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings, wherein:

[0016] Figure 1 It is a three-dimensional structural schematic diagram of the present invention;

[0017] Figure 2 It is an exploded schematic diagram of the present invention;

[0018] Figure 3 It is a cross-sectional view of the present invention. DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 3As shown, the present invention provides a spraying system of an upward spraying cold flame spraying machine, which aims to solve the problem of cold flame powder falling into the fan in the prior art and cause malfunction, and improve the spraying effect. The spraying system includes:

[0021] Nozzle 1: The nozzle 1 is arranged in the up-down direction, and a nozzle 11 is provided at its upper end for spraying cold flame. A cold flame input interface 12 is provided at the lower part of the side wall of the nozzle 1 for delivering cold flame powder and compressed air into the nozzle.

[0022] Bend pipe 2: The lower end of the nozzle 1 is not directly connected to the fan, but is connected to a curved bend pipe 2. The tail end of the bend pipe 2 is tilted upward to form a raised angle A. Figure 3 As shown, the fan 3 is connected thereto. This design raises the tail of the fan 3, effectively preventing the cold flame powder from falling into the fan due to gravity, and fundamentally solves the drawbacks existing in the traditional structure.

[0023] Fan 3: Provides an upward airflow for the system and sprays the cold flame upward. Preferably, the fan 3 adopts a brushless fan, which has the advantages of small size, low noise, and large air volume compared to the traditional brush blower. It can provide a more stable and powerful airflow and improve the spray effect. The tail end of the curved pipe 2 is preferably designed as a tapered mouth 21 that gradually decreases from the outside to the inside. The fan 3 is installed at the outer end of the tapered mouth 21, which can better guide the airflow and improve the efficiency of the fan.

[0024] Wind gathering section 13: In order to further enhance the spraying effect, a wind gathering section 13 is provided at the lower part of the nozzle 1 and below the cold flame input interface 12. The inner diameter of the wind gathering section 13 gradually decreases from bottom to top, which can effectively compress and accelerate the airflow, increase the wind pressure, thereby increasing the spray height and making the cold flame spray higher and farther.

[0025] Stator 4: In order to optimize the shape of the jet airflow and improve the spraying effect, a stator 4 is provided at the joint of the nozzle 1 and the curved pipe 2. The function of the stator 4 is to convert the vortex wind generated by the fan 3 into direct current wind. Specifically, the stator 4 includes at least one fixed air guide plate 41 arranged in the inner cavity of the nozzle 1 and extending along the length direction of the nozzle 1. The air guide plate divides the inner cavity of the nozzle 1 into a plurality of cavities, guides the airflow, makes it more uniform and stable, and finally forms direct current wind, thereby obtaining a better spraying effect. Experiments have shown that the application of direct current wind in cold flame spray machines can produce more ideal visual effects.

[0026] Through the above structural design, the spraying system of the present invention can effectively prevent cold flame powder from entering the fan, ensure the normal operation of the fan, extend its service life, and at the same time improve the spraying height and spraying effect.
