Technical Field

[0001] This utility model relates to the technical field of salt spray test chambers, specifically a salt spray test chamber with a cleaning effect. Background Technology

[0002] Salt spray test chambers use salt spray corrosion to test the corrosion resistance reliability of samples. They are typically used for accelerated corrosion simulation tests on metallic materials, protective coatings, components, electronic components, and industrial products. Salt spray refers to a diffuse system composed of tiny salt droplets in the atmosphere, and is one type of artificial environmental protection system. Many companies need to simulate the destructive effects of marine climates on their products, hence the development of salt spray test chambers. However, existing equipment suffers from the problem that the observation glass becomes a major absorbent of water droplets, which can obstruct the view as the test progresses.

[0003] Based on this, a salt spray test chamber with a cleaning effect is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] In one embodiment, such as Figures 1-6 As shown, a salt spray test chamber with cleaning effect includes an outer shell 1, a liquid storage mechanism 2 is provided on the top of the outer shell 1, an injection hole 3 is fixedly provided on the top of the liquid storage mechanism 2, a sealing door 5 is provided on the front of the outer shell 1, an observation glass 6 is provided on the inner wall of the sealing door 5, and a cleaning mechanism 7 is provided inside the sealing door 5.

[0026] In this embodiment, salt and water are added to the liquid storage mechanism 2 through the injection hole 3, and atomization begins. With the setting of the cleaning mechanism 7, when water droplets adhere to the observation glass 6, the cleaning mechanism 7 is activated to wipe the water droplets on the glass, solving the problem that water droplets easily adhere to the observation glass 6 during the test and affect the view.

[0027] In one embodiment, such as Figures 2-4 As shown, the cleaning mechanism 7 includes a fixed housing 701, a threaded rod 702, a threaded block 703, a limiting rod 704, a slider 705, a cleaning roller 706, and a servo motor 709.

The cleaning roller 706 is in contact with the observation glass 6. The servo motor 709 controls the raising and lowering of the cleaning roller 706 by rotating the threaded rod 702. The limiting rod 704 provides support, thereby causing the cleaning roller 706 to rotate and wipe the water droplets on the observation glass 6.

[0028] In one embodiment, such as Figure 4As shown, the surface of the cleaning roller 706 is provided with a cleaning cotton cloth 707, the surface of the cleaning roller 706 is provided with a hook and loop side, and the back of the cleaning cotton cloth 707 is provided with a hook and loop side, so that the cleaning cotton cloth 707 can be easily removed and cleaned through the hook and loop.

The transmission gears 708 mesh with each other, and the output end of the servo motor 709 is connected to the transmission gears 708. When the servo motor 709 rotates the transmission gears 708, it drives the threaded rod 702 to rotate synchronously.

[0030] In one embodiment, such as Figure 5 As shown, the liquid storage mechanism 2 includes a uniform tank 201. A conveying tank 202 is fixedly installed on the back side of the uniform tank 201. An extraction pump 203 is installed inside the conveying tank 202. The input end of the extraction pump 203 is connected to the uniform tank 201 through a conveying pipe 204. The output end of the extraction pump 203 is connected to a connecting component 205 through a conveying pipe 204. Several atomizing nozzles 206 are connected to the bottom of the connecting component 205. After the added salt and water are mixed in the uniform tank 201, the extraction pump 203 is activated to send the mixed salt water into the connecting component 205 through the conveying pipe 204. The salt water can be sent to the atomizing nozzles 206 through the connecting component 205 and sprayed out, thereby atomizing the test sample.

[0031] In one embodiment, such as Figure 1 As shown, a mounting base 8 is fixedly connected to the bottom of the inner wall of the outer shell 1, a support rod 9 is fixedly connected to the top of the mounting base 8, a placement plate 11 is fixedly connected to the top of the support rod 9, and a through hole 10 is opened on the top of the placement plate 11. The test sample is placed on the placement plate 11, and the through hole 10 opened on the placement plate 11 makes it easy for the bottom of the test sample to also come into contact with the salt spray.

[0032] In one embodiment, such as Figure 1 As shown, a mist vent 12 is provided on one side of the outer shell 1. The outer shell 1 is connected to the purification mechanism 4 through the mist vent 12. After the test, the residual mist in the chamber enters the purification mechanism 4 through the mist vent 12 for filtration and then is discharged into the air.

[0033] In one embodiment, such as Figure 1 and Figure 6As shown, the purification mechanism 4 includes a support base 401, a purification box 402 is fixedly installed on the top of the support base 401, an exhaust fan 405 is fixedly installed on the side of the purification box 402 away from the mist outlet 12, an exhaust port 406 is provided at one end of the exhaust fan 405, a fixing plate 403 is bolted between the purification box 402 and the exhaust fan 405, a filter screen 404 is provided inside the fixing plate 403, when the exhaust fan 405 is started, it generates suction, thereby drawing the mist into the purification box 402, then the mist is adsorbed and filtered through the filter screen 404, and finally discharged through the exhaust port 406. The filter screen 404 can be removed by removing the fixing plate 403 for easy cleaning and replacement.

[0034] The above embodiment discloses a salt spray test chamber with a cleaning effect. The test sample is placed on a placement plate 11, and the through-hole 10 in the placement plate 11 allows the bottom of the test sample to contact the salt spray. Salt and water are added to the storage mechanism 2 through the injection hole 3. After the salt water is mixed in the uniform tank 201, the extraction pump 203 is activated to send the salt water into the connecting component 205 through the delivery pipe 204. The connecting component 205 sends the salt water to the atomizing nozzle 206 for spraying, thereby atomizing the test sample. During the atomization process, the servo motor 709 and servo motor 700 can be used. When the transmission gear 708 is rotated, the threaded rod 702 rotates synchronously, thereby causing the threaded block 703 to drive the cleaning roller 706 to rise and fall. The limit rod 704 provides support, thus wiping away the water droplets on the observation glass 6, solving the problem that water droplets easily adhere to the observation glass 6 during the test and affect the view. After the test, the exhaust fan 405 is started to generate suction, thereby drawing the residual mist into the purification box 402. Then the mist is adsorbed and filtered through the filter screen 404, and finally discharged through the exhaust port 406. The filter screen 404 can be removed by removing the fixing plate 403 for easy cleaning and replacement.
