[0059] It should be noted that the composite salt spray test device described in the present invention is used for but not limited to the technical field of salt spray test equipment. For the convenience of explanation, in the present invention, only the application of the composite salt spray test device in the technical field of salt spray test equipment is used as an example for explanation. The principle of applying the composite salt spray test device to other types of equipment is essentially the same as the principle of applying it to the technical field of salt spray test equipment, and will not be described in detail here.

[0060] See also Figures 1 to 5 , Figure 1This is a structural schematic diagram of a composite salt spray test device in one embodiment of the present invention. A composite salt spray test device includes: a box body 1, a box door 2, a storage component 3, a salt spray generating component 4 and a defogger component 5. The interior of the box body 1 is hollow, the box door 2 is hinged to one side of the box body 1, and is provided with an observation window 21. The storage component 3 is built into the box body 1 and is rotatably connected to the box body 1. The salt spray generating component 4 is arranged above the storage component 3 and is connected to the box body 1. The defogger component 5 includes a defogger 51. The defogger 51 is built into the box body 1 and abuts against the observation window 21. One end of the defogger 51 is rotatably connected to the observation window 21, and the other end can swing back and forth within a preset angle relative to the observation window 21, so as to remove salt spray attached to the observation window 21.

[0061] In this device, the box door 2 is hinged to the box body 1 to facilitate the placement of materials to be tested. The storage component 3 is built into the box body 1 for placing materials to be tested. The salt mist generating component 4 is arranged above the storage component 3 for generating salt mist. The defogger 51 is in contact with the observation window 21, and one end of the defogger 51 is rotatably connected to the box door 2, and the other end can swing back and forth within a preset angle relative to the observation window 21 to remove the salt mist attached to the observation window 21.

[0062] Compared with the prior art, the defogger 51 is always in contact with the observation window 21 by swinging back and forth at a preset angle, so that the defogger 51 can remove the salt mist attached to the observation window 21 during the swinging process, thereby avoiding the salt mist blocking the user's vision during use, making it easier to observe the changes in the sample surface. This can solve the technical problem in the prior art that the observation window 21 is covered with water mist and the changes in the sample surface cannot be accurately observed through the observation window 21 from the outside, resulting in inconvenience in use.

[0063] Furthermore, the interior of the box body 1 in the present device is hollow, and an opening communicating with the interior thereof is provided on one side. The box door 2 is arranged relative to the opening, and one end of the box door 2 is hinged to the open end of the box body 1, and the other end is detachably connected to the open end of the box body 1. An observation window 21 is provided on the box door 2 to facilitate the user to observe the situation inside the box body 1. This is a conventional setting known to those skilled in the art and will not be elaborated on here.

[0064] Furthermore, the device can also be provided with a temperature sensor, a heater, a humidity sensor, a humidifier and a fan in the box body 1. Reference can be made to the Chinese utility model patent application number: CN201822187896.5, entitled: A composite salt spray test chamber. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0065] In this embodiment, Figure 1As shown, the box body 1 is provided with a second rotating hole, and the storage assembly 3 includes a storage plate 31, a second rotating shaft 32, a second transmission gear 33, a second driving gear 34 and a second driving motor 35. The storage plate 31 is arranged horizontally and is built into the box body 1. A plurality of through holes are provided on the surface of the storage plate 31. One end of the second rotating shaft 32 is connected to the storage plate 31, and the other end is rotatably inserted into the second rotating hole and is externally placed on the box body 1. The second transmission gear 33 is fixedly sleeved on the second rotating shaft 32, and the second driving gear 34 is rotatably connected to the box body 1 and meshes with the second transmission gear 33. The fixed end of the second driving motor 35 is connected to the box body 1, and the output shaft is connected to the second driving gear 34, which is used to drive the second rotating shaft 32 and the storage plate 31 to rotate around the axis of the first rotating shaft 53.

[0066] Driven by the second drive motor 35 , the material to be tested is prevented from rotating around the axis of the second rotating shaft 32 , so that the surface of the material to be tested can be evenly contacted with the salt spray, thereby improving the accuracy of the test.

[0067] In this embodiment, Figure 1 As shown, the salt mist generating component 4 includes a salt mist generator 41 and at least one nozzle component 42. The salt mist generator 41 is built into the box body 1. The nozzle component 42 includes a connecting pipe 421, a booster pump 422 and a plurality of nozzles 423. One end of the connecting pipe 421 extends and is connected above the storage plate 31. The liquid inlet end of the booster pump 422 is connected to the interior of the salt mist generator 41, and the liquid outlet end is connected to the other end of the connecting pipe 421. The plurality of nozzles 423 are evenly distributed along the extension direction of one end of the connecting pipe 421, and the interior of the nozzle 423 is connected to the interior of one end of the connecting pipe 421.

[0068] By arranging the salt mist generator 41, the connecting pipe 421, the booster pump 422 and the plurality of nozzles 423, the generated salt mist can be evenly contacted with the surface of the material to be tested, and the accuracy of the test is improved.

[0069] Furthermore, the user can select the number of nozzles 423 according to specific test conditions. Here, the salt spray generator 41, the connecting pipe 421, the booster pump 422 and the nozzle 423 are all conventional settings well known to those skilled in the art and will not be described in detail here.

[0070] In this embodiment, the demisting element 51 includes a connecting strip 511 and a demisting strip 512 , a plurality of elastic portions 513 , and a plurality of guide rods 514 .

[0071] Among them, such as Figures 2 to 5As shown, the connecting strip 511 is arranged relative to the observation window 21, and one end of the connecting strip 511 is rotatably connected to the box door 2, and the other end can swing relative to the observation window 21. The defogger strip 512 has a connecting end and an abutting end. The abutting end of the defogger strip 512 is elastic and abuts against the observation window 21. The connecting end of the defogger strip 512 is connected to the connecting strip 511.

[0072] The elastic abutting end abuts against the observation window 21 . When the connecting strip 511 swings relative to the observation window 21 , the elastic abutting end can scrape off the salt spray droplets on the observation window 21 and avoid damage to the observation window 21 .

[0073] Furthermore, the demisting strips 512 are common and easily purchased devices on the market, and are conventional settings well known to those skilled in the art, and will not be described in detail here.

[0074] In one embodiment, see Figure 6 The cross-sectional area of the abutting end of the demisting strip 512 gradually decreases in the direction approaching the observation window 21 .

[0075] The cross-sectional area tends to decrease gradually, which can improve the removal effect of salt mist.

[0076] In one embodiment, see Figures 2 to 5 A plurality of elastic portions 513 are spaced apart along the length direction of the connecting strip 511 , and one end of the elastic portion 513 is connected to the connecting strip 511 , and the other end is connected to the connecting end of the defogger strip 512 , so that the defogger strip 512 is always movable against the observation window 21 .

[0077] The elastic portion 513 is provided on the connecting strip 511 and the demisting strip 512 for generating an elastic restoring force so that the abutting end of the demisting strip 512 can always be pressed against the observation window 21 to ensure the removal effect of salt mist.

[0078] Furthermore, the elastic part 513 here is a spring, an elastic block and a spring sheet that are common and easy to purchase on the market. The spring, the elastic block and the spring sheet here are conventional settings well known to those skilled in the art and will not be described in detail here.

[0079] In one embodiment, see Figure 2 、 Figure 4 The connecting strip 511 is evenly provided with a plurality of guide holes along its length direction, and the guide rods 514 are arranged in one-to-one correspondence with the guide holes, and one end of the guide rod 514 is connected to the connecting end of the demisting strip 512, and the other end is slidably inserted into the guide hole.

[0080] The guide rod 514 and the guide hole play a guiding and connecting role in the sliding of the demisting strip 512 relative to the connecting strip 511 .

[0081] In this embodiment, the demisting assembly 5 further includes a sliding rod 52 , a first rotating shaft 53 , a first transmission gear 54 , a first driving gear 55 and a first driving motor 56 .

[0082] The door 2 is further provided with an arc-shaped sliding groove, one end of the sliding rod 52 is slidably embedded in the arc-shaped sliding groove, and the other end is connected to the connecting bar 511 .

[0083] The matching connection between the sliding rod 52 and the arc-shaped sliding groove enables the other end of the connecting bar 511 to be slidably connected to the door 2, thereby improving the stability of the device operation.

[0084] In one embodiment, see Figure 4 、 Figure 5 The box door 2 is provided with a first rotating hole, which passes through the box door 2. One end of the first rotating shaft 53 is connected to one end of the connecting bar 511, and the other end is rotatably inserted into the first rotating hole and is externally placed on the box door 2. The first transmission gear 54 is fixedly sleeved on the first rotating shaft 53, and the first driving gear 55 is rotatably connected to the box door 2 and meshes with the first transmission gear 54. The fixed end of the first driving motor 56 is connected to the box door 2, and the output shaft is connected to the first driving gear 55, which is used to drive the first rotating shaft 53 and one end of the connecting bar 511 to rotate around the axis of the first rotating shaft 53.

[0085] Driven by the output shaft of the first drive motor 56, the connecting bar 511, the defogger bar 512 and the first rotating shaft 53 rotate around the axis of the first rotating shaft 53. By the forward or reverse rotation of the first drive motor 56, the connecting bar 511 and the defogger bar 512 can be swung back and forth within a preset angle, thereby achieving the purpose of scraping off salt mist.

[0086] In this embodiment, Figure 1 As shown, the device further includes a control component 6 , which is connected to the box 1 and electrically connected to the salt spray generator 41 , the booster pump 422 , the first drive motor 56 and the second drive motor 35 .

[0087] The control component 6 is used to electrically connect the salt spray generator 41 , the booster pump 422 , the first drive motor 56 and the second drive motor 35 , thereby realizing automated and intelligent production of the test device.

[0088] Furthermore, the control component 6 in the present device is a common and easily purchased device on the market, and is a conventional setting well known to those skilled in the art, and will not be described in detail here.

[0089] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0090] The door 2 is hinged to the housing 1 to facilitate access to and placement of materials to be tested. The storage assembly 3 is built into the housing 1 for placing materials to be tested. The salt mist generating element 4 is disposed above the storage assembly 3 for generating salt mist. The defogger 51 abuts against the observation window 21. One end of the defogger 51 is rotatably connected to the door 2, while the other end can swing back and forth within a preset angle relative to the observation window 21 to remove salt mist adhering to the observation window 21. Compared to the prior art, the defogger 51, which swings back and forth within a preset angle, is always in contact with the observation window 21, allowing it to remove salt mist adhering to the observation window 21 during the swinging process, thus preventing salt mist from obstructing the user's vision during use and facilitating observation of changes in the sample surface.

[0091] The specific working process of the present invention is as follows: when in use, the user first places the material to be tested on the storage plate 31 and closes the box door 2. Then, the control component 6 controls the second drive motor 35 to drive the storage plate 31 to rotate. Then, the control component 6 controls the salt mist generator 41 to generate salt mist, and sprays it through the booster pump 422, the connecting pipe 421 and the nozzle 423. As the test continues, the salt mist continuously adheres to the observation window 21. When the user needs to observe the surface condition of the material to be tested, the control component 6 controls the first drive motor 56 to drive the connecting bar 511 and the demisting bar 512 to swing relative to the observation window 21, and remove the salt mist adhered to the observation window 21. The structure is simple and the operation is convenient.

[0092] The above structure of the device can solve the technical problem in the prior art that the changes on the sample surface cannot be accurately observed from the outside through the observation window 21 due to the observation window 21 being covered with water mist, thereby causing inconvenience in use.

[0093] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
