DETAILED DESCRIPTION

[0039] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in name as a way to distinguish components, but rather use differences in the functions of the components as the criteria for distinction. For example, the term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0040] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0041] The following is combined with Figures 1 to 12 The present invention is further described in detail with reference to the following specific embodiments, but is not intended to limit the present invention.

[0042] Example 1

[0043] A rotary nozzle comprises a base 1 and a turntable 2, the turntable 2 and one end of the base 1 are rotatably connected, a first cavity 3 is formed between the turntable 2 and the base 1, the first cavity 3 is used to accommodate powder, and the first cavity 3 has a discharge port 4 on one side close to the edge of the turntable 2, and the powder after being evenly spread flows out from the discharge port 4, the surface of the turntable 2 has at least one diverter tooth 21, and a plurality of diverter teeth 21 are arranged along the circumference of the surface of the turntable 2, and the diverter teeth 21 can be an arc-shaped structure, and the diverter teeth 21 are arranged in the first cavity 3, the interior of the base 1 has a feed channel 11, and the feed channel 11 is connected to the first cavity 3, and the surface of the base 1 has at least one through hole 12, and the through hole 12 is connected to the first cavity 3, and the powder flows out from the feed channel 11. The channel 11 enters the first cavity 3, and the gas enters the first cavity 3 from the through hole 12, and then pushes the diverter teeth 21 through the action of the airflow, thereby driving the turntable 2 to rotate. During the rotation, the diverter teeth 21 will stir the powder in the first cavity 3, and the stirred powder will become uniform, thereby improving the quality of the sprayed powder. The gas flowing in from the through hole 12 can also push the evenly stirred powder out of the first cavity 3. The powder flows in from the inlet of the base 1, passes through the feed channel 11 inside the base, and then flows to the turntable 2. The rotating turntable 2 makes the outflowing powder thin and evenly spread, and then the evenly flowing powder is pushed forward onto the surface of the workpiece through the discharge port 4, forming a paint film protection for the product. The base 1 is a structure in which a cylinder and a disc are connected. The disc and the turntable 2 together form a first cavity 3. The cylinder is used to introduce powder into the first cavity 3. There is a circle of feeding channels 11 around the inner side of the cylinder. The powder can pass through the feeding channels 11. This arrangement can make the powder flow into the first cavity 3 evenly, thereby improving the efficiency of the turntable 2 in stirring the powder, and also making the powder ejected from the discharge port 4 more uniform. The gas is blown into the first cavity 3 through the through hole 12, and the gas pushes the diverter teeth 21, thereby driving the turntable 2 to rotate. The rotating diverter teeth 21 dilute the powder evenly, so that the nozzle can discharge evenly diluted powder. This design eliminates the motor, which can effectively reduce the mass of the nozzle, allowing the user to hold the spray gun for a long time, improving the user's work efficiency.

[0044] In this embodiment, a shell 5 is also included, and the base 1 is installed in the shell 5. The side of the shell 5 has a first air inlet 51. The shell 5 and the base 1 form a second cavity 6, and the second cavity 6 is connected to the through hole 12 and the first air inlet 51 respectively. A plurality of through holes 12 are evenly arranged circumferentially on the surface of the base 1. This arrangement allows airflow to enter the first cavity 3 from multiple directions, thereby driving the turntable 2 to rotate faster, and the stirring force generated by the rotation is greater. In addition, the gas blown into the first cavity 3 is more uniform, making the powder blown out from the discharge port 4 more uniform. The gas can be blown into the second cavity 6 through the first air inlet 51, and then the gas is diverted from each through hole 12 to the first cavity 3, reducing the number of devices for blowing gas.

[0045] In this embodiment, a third cavity 7 and an air outlet 8 are defined between the housing 5 and the base 1. The air outlet 8 communicates with the third cavity 7. A separator 9 is provided between the third cavity 7 and the second cavity 6 to prevent airflow interference between the second cavity 6 and the third cavity 7. A second air inlet 52 is provided on the side of the housing 5, communicating with the third cavity 7. The second air inlet 52 blows air into the third cavity 7 and then out through the air outlet 8. The air blown out of the air outlet 8 can guide the powder blown out of the discharge port 4.

[0046] In this embodiment, at least one guide groove 13 is provided between the third cavity 7 and the air outlet 8. The guide grooves 13 are respectively connected to the third cavity 7 and the air outlet 8. A plurality of guide grooves 13 are provided along the circumference of the edge of the base body 1. A first protrusion 14 is provided between the guide grooves 13 and the third cavity 7. The provision of the guide grooves 13 can improve the consistency of the gas blown out of the air outlet 8. The first protrusion 14 can guide the gas, allowing the gas to flow out in the direction of the air outlet 8, thereby making the outflowing gas more directional.
