Description

Technical Field

[0001] This utility model relates to the technical field of paint sprayers, and in particular to a paint sprayer for preventing paint splattering using an outer alloy blade. Background Technology

[0002] A spray paint sprayer is a tool used for coating and spraying various surfaces. It typically uses compressed air to spray liquid paint onto the surface of an object, forming a uniform coating. The basic principle of a spray paint sprayer is to use air pressure to atomize the paint into fine particles, distributing them across the surface of the object to be coated, thus achieving the desired coating effect. Spray paint sprayers are widely used for surface coating of automobiles, furniture, home appliances, and industrial products. Common types of spray paint sprayers include spray guns and air-pressure spray guns, with different types suitable for different coating needs. The use of spray paint sprayers can improve coating efficiency, coating quality, and coating uniformity, and is widely used in industrial production and daily life.

[0003] In the prior art, traditional spray paint sprayers often produce a large number of splattered and atomized paint particles when spraying paint. These tiny paint particles fly in the air and cannot be completely concentrated on the surface of the target object. As the spraying operation continues, these paint particles may float in the air, causing air pollution. Workers can easily inhale these atomized paint particles during the operation. Long-term exposure to this environment may cause a series of serious health problems, especially lung diseases. Therefore, those skilled in the art provide a spray paint sprayer with a peripheral alloy blade to prevent paint splattering in order to solve the problems mentioned in the background art.

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Given that the current technology requires disassembling or installing multiple bolts one by one to disassemble or install the blind flange, the operation is not only time-consuming and labor-intensive, but also the bolts and gaskets of the blind flange are prone to deformation due to uneven stress after repeated disassembly and installation, which leads to sealing failure, resulting in pressure loss in the circulation pipeline and failure of pressure maintenance.

[0030] Please see Figures 1-2As shown, this utility model provides a technical solution: a paint sprayer for preventing paint splattering on an outer alloy knife, including a spraying mechanism 1 for connecting to an air pump and atomizing paint and spraying it onto the surface of the outer alloy knife, a paint storage component 2 for storing paint at the lower end of the spraying mechanism 1, and a baffle component 3 for isolating the atomized paint on one side of the paint storage component 2.

[0031] This paint sprayer effectively achieves paint atomization and spraying while preventing paint splatter through the coordinated operation of the spraying mechanism 1, paint storage component 2, and baffle component 3. First, gas enters the gas storage chamber 103 through the gas interface 102, connecting to the air pump, and drives the paint atomizing nozzle 104 to evenly atomize the paint and precisely spray it onto the outer alloy blade surface. The paint storage component 2 provides a stable paint flow, ensuring a continuous supply of paint and transmitting it to the spraying mechanism 1 at appropriate pressure. In addition, the baffle component 3 effectively blocks paint splatter after spraying, protecting the working environment and the safety of operators. The entire device not only improves the spraying quality but also greatly reduces paint waste and air pollution, increases work efficiency, and ensures the health and safety of workers.

[0032] As one implementation method in this embodiment, please refer to Figure 3 As shown, the spray painting mechanism 1 includes a gripping handle 101, a gas interface 102 fixedly sleeved inside the gripping handle 101, a gas storage chamber 103 fixedly connected to the upper end of the gripping handle 101, the gas output end of the gas interface 102 communicating with the inner cavity of the gas storage chamber 103, a spray atomizing nozzle 104 fixedly connected to the gas output end of the gas storage chamber 103, and an external threaded ring 105 fixedly connected to the center near the edge of the spray atomizing nozzle 104 on the side away from the gas storage chamber 103. An upper positioning post 106 is fixedly connected to the lower center of the gas storage chamber 103 away from the gripping handle 101. A hook 107 is fixedly connected to the upper center of the gas storage chamber 103 near the gas interface 102. A pressing handle 108 is rotatably connected to the lower center of the gas storage chamber 103. Two valve adjustment knobs 109 are arranged longitudinally on the side of the gas storage chamber 103 away from the paint atomizing nozzle 104. A material extraction port 1010 is provided on the lower side of the gas storage chamber 103.

[0033] The painting mechanism 1 consists of a gripping handle 101, a gas interface 102, a gas storage chamber 103, and a paint atomizing nozzle 104. It is responsible for atomizing and spraying paint onto the surface of the outer alloy blade. First, it is connected to an air pump through the gas interface 102. Gas enters the gas storage chamber 103, forming a high-pressure airflow. The gas is output from the gas storage chamber 103, pushing the paint in the paint atomizing nozzle 104 and spraying it out through the fine holes of the paint atomizing nozzle 104. The paint atomizing nozzle 104 ensures uniform atomization of the paint, thereby improving the painting effect. In addition, the upper positioning post 106 at the lower end of the gas storage chamber 103 and the pressing handle 108 jointly control the amount of paint sprayed, ensuring the stability and accuracy of the painting. The air valve adjustment knob 109 allows the gas flow rate to be adjusted as needed, further optimizing the painting effect. Overall, the painting mechanism 1 effectively atomizes and sprays paint onto the target surface, improving work efficiency and painting quality.

When gas is pressurized through the gas storage chamber 103, paint enters the paint transfer pipe 203 through the extraction port 1010 and is finally sprayed through the paint atomizing nozzle 104. The air pressure regulating knob 205 on the sealing cap 202 can control the pressure of the paint flow to ensure smooth and stable spraying. The paint storage assembly 2 is easy to maintain and clean due to its detachable connection design, which further improves the service life of the equipment.
