[0002] In the field of mechanical production and processing, after the product is formed and produced by processing equipment, the workpiece needs to be sprayed on the surface. The paint is atomized and then sprayed on the surface of the product under the drive of airflow, so as to play an important role in protecting the workpiece during processing and achieve the effects of corrosion and oxidation resistance. On the other hand, different paints have different colors and characteristics. After spraying according to needs, it not only improves the aesthetics but also achieves the corresponding protection effect. The following problems exist in the existing technology:

[0003] 1. The existing spraying device with protective function uses the spray nozzle to spray the product surface at a wide angle. The spraying range is not limited, which may lead to excessive spraying range, resulting in waste of surrounding paint or injury to the human body. In addition, the nozzle part is generally externally arranged and does not have a storage protection function. When it falls or is hit, the nozzle part is damaged, affecting its use;

[0004] 2. The existing spraying device with protective function sprays the paint on the surface of the product through a spray nozzle after atomizing the paint. The paint is easy to solidify when used for a long time, which affects the effect of the overall spraying. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments: Example 1

[0024] like Figure 1-5 As shown, the utility model provides a spraying device with a protective function, including a shell 1, characterized in that: a handle 2 is fixedly connected to the bottom of the shell 1, an extraction pump 4 is fixedly installed inside the shell 1, an electric telescopic rod 5 is fixedly installed at the upper end inside the shell 1, a sliding seat 6 is movably installed at the front end inside the shell 1, the sliding seat 6 is slidably connected to the shell 1, a bellows 7 is fixedly connected between the extraction pump 4 and the sliding seat 6, a nozzle 8 is fixedly installed on the front side of the sliding seat 6, and an adjustment mechanism 9 is fixedly installed on the front side of the sliding seat 6;

[0025] The adjustment mechanism 9 includes a mounting ring 901, which is fixedly mounted on the front side of the sliding seat 6. An inner baffle plate 902 and an outer baffle plate 903 are fixedly mounted on the front side of the mounting ring 901. Damping rods 904 are installed at the four corners of the front side of the sliding seat 6. The damping rod 904 is slidably connected to the sliding seat 6. A limiting ring 905 is fixedly mounted on the front end of the damping rod 904.

[0026] In this embodiment, an electric telescopic rod 5, a sliding seat 6, a bellows 7, a nozzle 8, etc. are provided. By operating the adjustment button 10, the front end of the electric telescopic rod 5 is extended to drive the sliding seat 6 to slide outward along the front side of the shell 1. When the electric telescopic rod 5 is extended to the limit, the front side of the sliding seat 6 accurately blocks the front side of the shell 1 and extends the nozzle 8 to the outside of the shell 1. At the same time, during the sliding process of the sliding seat 6, the bellows 7 is driven to expand and contract synchronously, and the nozzle 8 located inside the shell 1 is driven to expand and contract through the coordinated action, so as to protect the nozzle 8 when it is placed. The protective function is achieved by installing the ring 901, the inner baffle plate 902, the outer baffle plate 903, the damping rod 904 and the limiting ring 905. The limiting ring 905 is adjusted to drive the damping rod 904 to move and control the length of the damping rod 904 located in front of the sliding seat 6. The inner baffle plate 902 and the outer baffle plate 903 are limited by the limiting ring 905. When the position of the limiting ring 905 is adjusted, the limiting ring 905 is moved forward and backward to make the inner baffle plate 902 and the outer baffle plate 903 expand outward or contract inward, thereby achieving the effect of limiting and adjusting the spraying range of the nozzle 8. Example 2

[0027] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a preheating barrel 3 is fixedly installed at the bottom of the shell 1, and the upper end of the preheating barrel 3 penetrates the bottom of the shell 1 and is connected to the extraction pump 4;

[0028] The preheating barrel 3 includes an inner barrel body 301 , an outer barrel body 302 , a material injection port 303 and a heating coil 304 . The heating coil 304 is fixedly installed between the inner barrel body 301 and the outer barrel body 302 , and the material injection port 303 is fixedly installed at the bottom of the inner barrel body 301 .

[0029] In this embodiment, through the arrangement of the inner barrel body 301, the outer barrel body 302, the injection port 303, and the heating coil 304, the paint is sucked into the inner barrel body 301 after being connected through the injection port 303, and the heating coil 304 is turned on by operating the adjustment button 10 to heat the outer wall of the inner barrel body 301 to prevent the paint inside the inner barrel body 301 from solidifying and becoming viscous. At the same time, the inner barrel body 301 and the outer barrel body 302 are isolated from the outside to reduce heat loss.

[0030] The working principle of the spray device with protective function will be described in detail below.

[0031] like Figure 1-5As shown, after the device is electrically connected and connected to the paint tube through the injection port 303, the front end of the electric telescopic rod 5 is extended by operating the adjustment button 10 to drive the sliding seat 6 to slide outward along the front side of the shell 1. When the electric telescopic rod 5 is extended to the limit, the front side of the sliding seat 6 accurately blocks the front side of the shell 1 and makes the nozzle 8 extend outside the shell 1. At the same time, during the sliding process of the sliding seat 6, the bellows 7 is driven to expand and contract synchronously. The paint is sucked into the inner barrel 301 through the injection port 303 by starting the extraction pump 4. The heating coil 304 is turned on by operating the adjustment button 10. The outer wall of the inner barrel body 301 is heated to prevent the paint inside the inner barrel body 301 from solidifying and becoming viscous, and then the damping rod 904 is driven to move toward the inside of the sliding seat 6 by pushing the limit ring 905 to control the length of the damping rod 904 located at the front side of the sliding seat 6, and the inner baffle 902 and the outer baffle 903 are limited by the limit ring 905. The limit ring 905 moves backward to make the inner baffle 902 and the outer baffle 903 expand outward, so that the opening diameter on the front side of the inner baffle 902 and the outer baffle 903 is enlarged, and the paint is atomized by pressing the start switch 11 and sprayed outward from the nozzle 8.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
