[0004] The test device in the aforementioned patent operates through a sprayer under the support plate. The number of sprayers needs to be manually increased to adjust the spray angle for salt spray testing. However, after the sprayer finishes its work, the water droplets condensed on the box will pass through the support plate and gather into a water flow under the support plate. The water may contain impurities and oil, which may clog the spray nozzles of the sprayer. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable-angle salt spray test device. A sliding groove is provided on the inner wall of the chamber, and the sprayer can move on the sliding groove to spray out the solution. At the same time, the solution sprayed by the sprayer forms water droplets and then collects into a water flow. The water may contain impurities and oil, which will reduce the clogging of the spray nozzle.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-9 This utility model provides an adjustable angle salt spray test device, including a box body 1. A transparent box cover 6 is snapped onto the top of the box body 1. At the same time, a storage box 4 is movably connected to the transparent box cover 6. A feed inlet 3 is provided on one side of the storage box 4, while an operation screen 2 is provided on one side of the box body 1, and an electric push cylinder 7 and a U-shaped tube 5 are provided on the other side of the box body.
[0024] By adopting the above technical solution, the material inside the box 4 can be observed through the transparent box cover 6. At the same time, the transparent box cover 6 can be opened and closed by controlling the raising and lowering of the electric cylinder 7 on the operation screen 2, making the operation of the staff more labor-saving.
[0025] In this embodiment of the utility model, the interior of the box 1 is provided with fixed columns 14 arranged in a rectangular array. A bushing wheel 11 is fixedly connected to the fixed column 14, and a circular hole groove 111 is opened on the bushing wheel 11. A connecting rod 132 is movably connected to the center of the bushing wheel 11. The connecting rod 132 is fixedly connected to a rectangular frame 13, and a hanging rod 131 arranged in a rectangular array is provided in the rectangular frame 13. The hanging rod 131 is fixedly connected to the rectangular frame 13.
[0026] By adopting the above technical solution, the experimental material is hung on the hanging rod 131, and the angle of the connecting rod 132 of the bushing wheel 11 is adjusted to drive the angle of the material on the hanging rod 131 to shift, and the experiment can then begin.
[0027] In this embodiment of the utility model, the inner wall of the housing 1 is provided with a sliding groove 15, and a sprayer 151 is movably connected in the sliding groove 15. A stud 1512 is connected in the middle of the sprayer 151. The stud 1512 can be snapped into the sliding groove 15, and a spray nozzle 1511 distributed in a ring array is opened on one side of the sprayer 151. A load-bearing plate 13 is provided at the lower end of the housing 1. The load-bearing plate 13 is provided with a drainage hole 161 distributed in a rectangular array. A fan 12 is provided at the end of the housing 1 near the operation screen 2.
[0028] By adopting the above technical solution, the sprayer 151 is located in the middle of the inner wall of the box. The water droplets condensed after spraying at the spray nozzle 1511 are reduced, thereby reducing the chance of water droplets flowing into the spray nozzle 1511 and reducing the clogging of the spray nozzle 1511 due to impurities and oil.
[0029] In this embodiment of the utility model, the U-shaped tube 5 is movably connected to the storage tank 4. Meanwhile, the storage tank 4 includes a filter tank 43, a storage tank 42 and an electrical box 41 inside. The filter tank 42 is provided on one side of the storage tank 4, while the electrical box 41 is provided on the side near the feed inlet 3. The storage tank 42 is provided between the electrical box 41 and the filter tank 43.
[0030] By adopting the above technical solution, the water flowing below the support plate 16 enters the filter tank 43 through the U-shaped pipe 5 to filter out impurities and oil in the water flow, and then flows into the storage tank 42 for the next test.
[0031] The working principle of this utility model is as follows: First, using the operating screen 2, the electric pusher 7 opens the transparent box cover 6, allowing the experimental materials to be hung on the material hanging tube 131. Simultaneously, the stud on the bushing wheel 2 is unscrewed, the angle of the rectangular frame 13 is adjusted, and then the stud is screwed back on. The material hanging tube 131 is moved as the angle of the rectangular frame 13 is adjusted. Then, the position of the sprayer 151 on the slide 15 is adjusted to the required experimental position. This reduces contact with condensed water droplets, preventing clogging of the spray nozzle. After closing the transparent box cover 6, the solution is poured into the inlet 3. The operating screen 2 is then used, and the solution... The electric pump in the air box 41 delivers the solution to the sprayer 151 via a hose. The solution is sprayed out in the sprayer via the control panel 2 to conduct the salt spray test. The material condition inside the box 1 is observed through the transparent box 6 cover. After the test, the mist condenses into water droplets. The fan 12 is started on the control panel 2. The air volume of the fan 12 is first reduced to condense the mist into water droplets, and then the air volume is increased to collect the water droplets through the drain hole 161 under the load-bearing plate 13. Then, it enters the filter tank 43 through the U-shaped tube 5. After filtration, it enters the storage tank 42. For the next test, the solution is delivered to the sprayer 151 via the electric pump in the electric box 41. When no longer in use, the U-shaped tube 5 is removed and the solution is discharged.
