Description

Technical Field

[0001] The utility model relates to the technical field of spray heads, and more specifically to an electric rotating spray head. Background Art

[0002] With the upgrading of domestic industries, more and more automotive parts / precision electromechanical products require non-contact cleaning (reference publication number CN115739826A) during the assembly process, such as the three-electric system and other parts (headlights, automotive instruments / controllers, PCBA, etc.); the dust blowing devices currently on the market mainly include air knives and pneumatic rotary nozzles.

[0003] The shortcomings of the prior art: The above two dust blowing devices have certain limitations in practical applications, which are described in detail below.

[0004] 1. Wind knife: It cannot generate pulsed airflow, resulting in poor cleaning effect; and its size is generally large, so it cannot enter the cavity for cleaning. It is difficult to apply it to the cleaning of automotive parts (often complex curved / special-shaped customized parts, and very few regular products).

[0005] 2. Pneumatic rotary nozzle: compressed air is used to drive the nozzle to rotate and blow air at the same time, but the rotation speed is fixed and cannot be adjusted (determined by the design size and processing accuracy, the failure rate is high and cannot be reproduced); the fluctuation of air pressure will affect the rotation speed and dust pressure at the same time, which means that the optimal process parameters and cleaning effect cannot be obtained in actual cleaning applications. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides an electric rotating spray head to solve the problems existing in the above background technology.

[0007] The utility model provides the following technical solution: an electric rotating spray head, comprising a mounting base, a rotating component rotatably mounted on the top of the mounting base, a traction assembly fixedly mounted on the surface of the rotating component, an air outlet nozzle fixedly mounted on the top of the rotating component, the traction assembly is used to drive the rotating component to rotate around its own axis, and the air outlet nozzle is used to spray a strong airflow outward.

[0008] Preferably, the rotating component consists of a vertical section and a horizontal section. A first channel is opened in the vertical direction inside the vertical section, and a second channel is opened in the horizontal direction inside the horizontal section. Two second channels are symmetrically arranged, and the first channel is connected to the second channel.

[0009] Preferably, the traction assembly includes a magnetic ring and a bearing, the magnetic ring is fixedly mounted on the vertical section surface of the rotating component, a coil winding is fixedly mounted on the outer surface of the magnetic ring, the vertical section of the rotating component is rotatably connected to the inside of the mounting base via a bearing, and a sealing ring is installed on the top of the coil winding.

[0010] Preferably, two of the gas outlet nozzles are symmetrically arranged corresponding to the second channel, and the gas outlet nozzles are connected to the second channel.

[0011] Preferably, a cable connector is installed on the surface of the mounting base, and the cable connector is used to provide current to the coil winding.

[0012] Technical effects and advantages of the utility model:

[0013] 1. When the utility model is in use, the cable connector can be connected to an external power source and provide current to the coil winding. When the current flows through the coil winding, a magnetic field force can be generated. The magnetic field force can drive the magnetic ring to rotate around its own axis. The magnetic ring rotates and drives the rotating part to rotate synchronously around its own axis, thereby realizing the rotational movement of the air outlet nozzle. The staff can accurately control the size of the magnetic field force by controlling the size of the current, and then accurately control the rotation speed and output torque of the rotating part and the air outlet nozzle. In addition, the rotation speed and airflow pressure of the utility model can be independently controlled and adjusted without interfering with each other, thereby improving the precision of the adjustment.

[0014] 2. The vertical and horizontal sections of the rotating component are hollow in design. Compressed air can be input from the bottom of the first channel and transported to the air outlet nozzle through the second channel. The air outlet nozzle has a tiny aperture inside. The compressed air entering the tiny aperture can form a strong airflow, which is then ejected outward. By increasing the electromagnetic force to drive the nozzle to rotate, the air flow channel design is simplified, which can greatly reduce the difficulty of processing.

The vertical section of the rotating component 2 is rotatably connected to the inside of the mounting base 1 through the bearing 33. A sealing ring 34 is installed on the top of the coil winding 31.

Compressed air is input from the bottom of the first channel 21 and transported to the air outlet nozzle 4 through the second channel 22. The air outlet nozzle 4 has a tiny aperture inside.
