Salt spray refers to the dispersion system composed of tiny salt droplets in the atmosphere. It is one of the three-proof series of artificial environments. Many companies need to simulate the destructiveness of the ocean climate to the products, so the salt spray test chamber came into being. Salt spray test chambers are divided into neutral salt spray and acidic salt spray. The difference lies in the different standards and test methods. It is also known as the "NSS" and "CASS" tests. It is the most common test method in the artificial three-proof climate.

[0003] In the prior art, there is a salt spray test machine with Chinese patent number CN219455878U, which includes a salt spray test machine, a control console, an experimental chamber and a bearing chamber, wherein a salt spray nozzle and a heating port are arranged in the experimental chamber, a bearing chamber is provided on the rear outer wall of the salt spray test machine, a modulation tank, a motor, a solution tank and a distilled water tank are installed in the bearing chamber, the pH value of the solution in the modulation tank is detected by a pH sensor, when the pH value is less than a preset value, a solenoid valve arranged at the bottom of the solution tank is used to adjust the concentration of the solution by adding dilute hydrochloric acid or sodium hydroxide solution to the modulation tank and controlling the addition of distilled water by the solenoid valve of the distilled water tank, so that the pH value of the solution before atomization can be automatically adjusted, thereby greatly improving the degree of automation of the salt spray test machine.

[0004] However, although the prior art has many technical advantages, the disadvantage is that during use, the above-mentioned salt spray test machine cannot classify and place test workpieces of different specifications and styles due to the lack of a placement mechanism.

[0027] Working principle:

[0028] When in use, the support leg 1 supports the entire chassis 2. First, the power is turned on, and then the clean water, laboratory water and salt water in the pressure barrel are added respectively according to the indicator light. Then, a placement mechanism 5 is set, wherein a larger workpiece can be placed on the partition 52, and the step column 53 can support the workpiece to increase the salt spray contact area. The through hole opened on the partition 52 further ensures the contact surface between the workpiece and the salt spray.

[0029] After placement is completed, the box cover 22 is closed by the handle of the box cover 22 under the action of the hinge, so that the box cover 22 contacts the bottom of the sealing groove 211, and the sealing groove 211 is filled with water to seal, so that the salt mist and acid mist do not leak from between the box cover 22 and the box body 21.

[0030] The control panel 3 is used to control the salt spray test machine to start working. The salt spray is sprayed from the spray column 23, and after contacting the mist expansion mechanism 4, it spreads to the surroundings through the mist expansion cone 43. After the test is completed, when the test machine stops working, the box cover 22 is opened. By setting the protection mechanism 6, when the box cover 22 rotates to contact the silicone plate 64, the silicone plate 64 is affected by the gravity of the box cover 22 and moves downward to squeeze the compression spring 62.

At the same time, the box cover 22 is supported to limit its maximum rotation angle, so as to facilitate the cover. The compression spring 62 and the damping rod 63 are fixed to the back of the box body 21 by the bracket 61. After taking out the workpiece sample, the sealing plug 212 is then pulled out from the sealing hole 2111 under the action of the sliding connection, and the clean water in the sealing groove 211 is drained into the box body 21, and then all the waste liquid is discharged through the internal drain port.

[0031] When maintenance and overhaul is required, the contact end can be moved away from the spray column 23 by rotating the connecting bolt 44. When the connecting bolt 44 is no longer in contact with the spray column 23, the static friction between the two is zero, and the sliding ring 41 can slide on the spray column 23, thereby driving the vertical rod 42 and the mist expansion cone 43 to move upward. The mist expansion mechanism 4 can be removed by sliding upward. At this time, the partition 52 can also be slid out from the support column 51, thereby facilitating the maintenance of the components below the partition 52.
