Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to a spraying preheater. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the paint into uniform and fine droplets with the help of pressure or centrifugal force, and then applies it to the surface of the object to be coated. However, the existing spraying process is to spray the paint on the surface of the product and then dry it. Because the air temperature is generally low, the paint generally contains more water, and the paint is unevenly dispersed during the spraying process, and it is easy to form clumps. The paint on the surface of the product forms slowly, and the surface of the product is relatively rough, resulting in the following shortcomings: 1. The paint surface takes a long time to dry. 2. The paint surface is not easy to form outdoors or in humid weather. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Summary of the invention

[0004] The present invention is achieved through the following technical solutions:

[0005] A spray preheater comprises a shell, one end of which is equipped with a quick-connect male joint, the other end of which is equipped with a quick-connect female joint, a heating element is installed on the inner side of the shell, the inner side of the heating element is provided with a channel connected to the quick-connect male joint and the quick-connect female joint, the end of the heating element is provided with a touch seat electrically connected to the heating element, the inner side of the touch seat is connected to the channel, a contact plate is hinged on the touch seat, one end of the contact plate extends to the inner side of the touch seat, the touch seat is provided with a contact point corresponding to the other end of the contact plate, and a return spring is connected between the middle part of the contact plate and the touch seat.

[0006] Furthermore, a power supply slot electrically connected to the heating element is provided on the outer side of the shell.

[0007] Furthermore, a fixing ring for mounting the starting end of the heating element is provided at one end of the shell.

[0008] Furthermore, a first connection seat for installing the quick-connect male connector is provided at one end of the shell, and a first gasket is provided at the contact point between the first connection seat and the shell.

[0009] Furthermore, a second connection seat for installing the quick-connect female connector is provided at the other end of the shell, and a second gasket is provided at the contact point between the second connection seat and the shell.

[0010] Furthermore, the contact plate is provided with a hinge shaft hinged to the touch base.

[0011] Furthermore, the touch base is provided with an articulation groove for the articulation shaft to articulate.

[0012] Furthermore, a circular contact piece is provided at one end of the contact plate.

[0013] Furthermore, one end of the return spring is welded to the touch seat, and the other end of the return spring is welded to the contact plate.

[0014] Furthermore, the touch seat is provided with a contact plate limiting installation groove for positioning and installing the contact plate.

[0015] Compared with the prior art, the present invention installs a heating element on the inner side of the shell, and the inner side of the heating element is provided with a channel connected with the quick-connect male connector and the quick-connect female connector. The end of the heating element is provided with a touch seat electrically connected to the heating element, and the touch seat is hinged with a contact plate, and the touch seat is provided with a contact point corresponding to the other end of the contact plate. A reset spring is connected between the middle of the contact plate and the touch seat. When in use, the air pressure pipe is connected to the quick-connect male connector, and then the spray gun is connected to the quick-connect female connector. After the power is turned on and the spray gun is pressed, the contact plate is pushed by the airflow to contact the contact point. The spray preheater starts to work and heats. After you stop pressing the spray gun, the reset spring resets the contact plate and the spray preheater stops working, making the spraying process simple, reducing the moisture in the paint, accelerating the formation of surface paint, and making the paint disperse better during spraying without forming clumps, reducing surface roughness, and can be used in outdoor or humid weather environments. At the same time, the contact spray preheater directly heats the temperature of compressed air. After installation, it will not affect the working efficiency of the original equipment even if it is not used or unplugged. It is simple and quick to install, easy to use, and has a good user experience. BRIEF DESCRIPTION OF THE DRAWINGS
