[0027] like Figure 1-6 As shown, in some illustrative embodiments, a salt spray chamber is provided, including: a corrosion test chamber 100, an adjustment mechanism 200, a drying mechanism 300, and a cleaning mechanism 400.

[0028] The corrosion test chamber 100 provides a closed, controlled salt spray environment. Made of corrosion-resistant materials, it is equipped with a salt solution reservoir, heating device, spraying device, and control device to simulate the corrosive conditions of marine or other saline environments. Its internal space accommodates the test samples and maintains constant temperature, humidity, and salt spray concentration. A cleaning mechanism 400 is located at the front of the corrosion test chamber 100 for rinsing the interior. A drying mechanism 300 is located at the rear of the corrosion test chamber 100 for drying the rinsed interior. An adjustment mechanism 200 is located at the top of the corrosion test chamber 100 to drive the nozzle portion of the cleaning mechanism 400 and the air outlet portion of the drying mechanism 300 to move up and down, thereby achieving comprehensive cleaning and drying of the interior of the corrosion test chamber 100.

[0029] The corrosion test chamber 100 includes: a test chamber body 110, a feeding port 120, a sealing cover plate 130, and a support column 140.

[0030] A feed port 120 is located on the top panel of the test chamber 110 for adding salt solution or other corrosive media into the chamber. A discharge trough 150 is provided on the side of the test chamber 110 for discharging waste liquids generated during the test, such as excess salt solution or corrosion products. A sealing cover 130 is disposed within the discharge trough 150; specifically, the sealing cover 130 can be partially embedded within the discharge trough 150 to achieve closure.

[0031] The adjustment mechanism 200 includes: an electric telescopic rod 210, a controller 220, and a mounting bracket 230.

[0032] The electric telescopic rod 210 is driven by an electric motor, which converts rotational motion into linear motion to achieve its telescopic function. Specifically, the electric motor, after gear reduction, drives a screw and nut mechanism to convert rotational motion into linear motion of the telescopic rod, thereby enabling the up-and-down movement of the moving end of the electric telescopic rod 210. A controller 220 is installed on the top of the electric telescopic rod 210. The controller 220 controls the movement of the electric telescopic rod 210 and can control the telescopic speed, travel range, and stop position of the electric telescopic rod 210 through a preset program or manual operation. The fixed end of the electric telescopic rod 210 is installed on the top panel of the test chamber 110. A mounting bracket 230 is installed on the moving end of the electric telescopic rod 210 and is located inside the corrosion test chamber 100, serving to support the nozzle part of the cleaning mechanism 400 and the air outlet part of the drying mechanism 300.

[0033] Under the control of the controller 220, the electric telescopic rod 210 enables the nozzle part of the cleaning mechanism 400 and the air outlet part of the drying mechanism 300 to move up and down along the inner wall of the test chamber, achieving comprehensive cleaning and drying of the inner wall. Simultaneous cleaning and drying make the cleaning process of the salt spray chamber more compact and efficient. All components of the adjusting mechanism 200 are installed on the top of the test chamber body 110, without occupying internal space, ensuring the effective usable area of ​​the corrosion test chamber 100.

[0034] The cleaning mechanism 400 includes: a nozzle 401, a water tank 402, a water pump 403, a water pumping pipe 404, a diverter seat 405, a diverter pipe 406, a pressure booster 407, a fixed pipe 408, a guide pipe 409, a flexible water supply pipe 410, a water inlet 411, and a cleaning brush 412.

[0035] The nozzle 401 is mounted on the mounting bracket 230. The nozzle 401 has a rectangular frame structure with an internal cavity and water outlet holes on its outer walls. The water storage tank 402 is located at the front end of the test chamber body 110 and is used to store cleaning solution or water. The water pump 403 is located on top of the water storage tank 402 and is used to extract the cleaning solution from the water storage tank 402 and transport it to the water pumping pipe 404. The two ends of the water pumping pipe 404 are connected to the outlet of the water pump 403 and the diverter seat 405, respectively. The diverter seat 405 is connected to the diverter pipe 406 and is used to divert the cleaning solution to different diverter pipes 406.

[0036] The guide pipe 409 is connected to the diversion pipe 406. A pressure booster 407 and a fixed pipe 408 are mounted on the top panel of the test chamber 110. The pressure booster 407 is connected to the guide pipe 409 and is used to pressurize the cleaning fluid to improve the cleaning effect. The fixed pipe 408 is connected to the pressure booster 407, and an elastic water supply pipe 410 is connected to the fixed pipe 408. The fixed pipe 408 is used to transport the pressurized cleaning fluid, and the elastic water supply pipe 410 is used to transport the pressurized cleaning fluid to the nozzle 401. The nozzle 401 is connected to the elastic water supply pipe 410. A water inlet 411 is located on the water storage tank 402 and is used to inject cleaning fluid or water into the water storage tank 402. A cleaning brush 412 is located on the nozzle 401 and is used to assist in cleaning the inner wall of the test chamber 110.

[0037] When the corrosion test chamber 100 needs to be rinsed, the water pump 403 is turned on. The water pump 403 draws out the cleaning solution or water inside the water storage tank 402 and delivers it to the diversion seat 405 through the water pumping pipe 404. The diversion seat 405 branches the water flow and delivers it to each pressure booster 407 through the diversion pipe 406. The pressure booster 407 pressurizes the water and finally sprays it out through the nozzle 401 to rinse the inner wall of the test chamber 110. The top of the nozzle 401 is equipped with a cleaning brush 412. The nozzle 401 and the cleaning brush 412 can move up and down under the action of the adjustment mechanism 200. During the movement, the inner wall of the test chamber 110 can be scrubbed.

[0038] The cleaning fluid is pressurized by the pressure injector 407, increasing its impact force and effectively removing salt deposits and other stains from the inner wall. The auxiliary scrubbing function of the cleaning brush 412 further enhances the cleaning effect, ensuring a thorough cleaning of the inner wall. The various components of the cleaning mechanism 400 are rationally arranged, without occupying excessive space, ensuring the effective usable area of ​​the test chamber.

[0039] The drying mechanism 300 includes: a drying air outlet 310, an air conveying channel 320, a flexible air conveying duct 330, a fan 340, and a mounting base 350.

[0040] The drying air outlet 310 is located at the bottom of the mounting bracket 230. The drying air outlet 310 is hollow inside. The drying air outlet 310 is provided with air outlet channels 311 facing the inner wall of the test chamber 110 around its perimeter. The air outlet channels 311 serve as the outlet for drying hot air. The hot air is evenly distributed to the inner wall of the test chamber through the air outlet channels 311 to ensure the drying effect.

[0041] An air supply channel 320 is installed on the drying outlet end 310, and both ends of the air supply channel 320 are connected to the flexible air supply duct 330 and the internal space of the drying outlet end 310, respectively. The flexible air supply duct 330 has a certain degree of elasticity, which facilitates installation and position adjustment. There are four air supply channels 320, and the four air supply channels 320 are arranged in a matrix on the top of the drying outlet end 310. A through slot is opened on the top panel of the test chamber 110. The air supply channels 320 pass through the through slot and are connected to the flexible air supply duct 330. The flexible air supply duct 330 is connected to the air outlet of the fan 340.

[0042] A support platform 160 is provided at the bottom rear end of the test chamber body 110. The fan 340 is mounted on the support platform 160. The mounting base 350 is located on top of the fan 340. The mounting base 350 is hollow inside. The internal space of the mounting base 350 is connected to the air outlet of the fan 340 and the flexible air duct 330.

[0043] After cleaning, the fan 340 is turned on, generating hot air. This hot air is delivered to the drying outlet 310 via the mounting base 350, flexible air duct 330, and air delivery channel 320. The outlet channel 311 of the drying outlet 310 evenly distributes the hot air onto the inner wall of the test chamber 110, achieving comprehensive drying. The matrix arrangement of the air delivery channels 320 and outlet channels 311 ensures uniform coverage of the inner wall with hot air, improving drying efficiency. The rational layout of the drying outlet 310, air delivery channel 320, and flexible air duct 330 results in a short and direct hot air transmission path, reducing energy loss. This helps maintain the cleanliness of the inside of the test chamber 110, preventing the accumulation of dirt and salt crystals, thereby extending the equipment's service life. Overall operation is simple and convenient.
