[0002] Paint is a material that covers the surface of an object, protecting it and enhancing its appearance. Therefore, paint is widely used in construction, industry, automobiles, and aerospace. Salt spray testing machines can evaluate the rust prevention ability of paint in a salt spray environment, aiming to improve the product quality of paint.
[0003] However, existing salt spray machines for paint testing have the following problems:
[0004] Since the device will malfunction when the salt solution runs out, thus affecting the testing of coatings, the device needs to remind the user to replenish the salt solution before it runs out. However, existing salt spray machines for coating testing do not easily remind users when the salt solution is almost depleted, which can easily affect the testing of coatings and reduce the practicality of the device.
[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing salt spray tester for paint testing. Utility Model Content
[0006] The purpose of this invention is to provide a salt spray tester for coating testing, in order to solve the problem mentioned in the background art that existing salt spray testers for coating testing do not easily remind users when the salt solution is almost used up, which can easily affect the testing of coatings and reduce the practicality of the device.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a salt spray tester for coating testing, comprising a base plate, a heating mechanism, a delivery pump, an atomizing nozzle, a trigger switch, and an alarm mechanism. A salt spray chamber and a solution tank are respectively fixed to both ends of the upper surface of the base plate. A cover is installed on the upper end of the salt spray chamber, and a support is fixedly connected to the inner wall of the salt spray chamber.

A guide wheel is provided on the upper surface of the solution chamber on the side of the end cap, and a pull rope is movably connected to the outer wall of the guide wheel. A float and a block are fixed to the two ends of the pull rope, respectively. A trigger rod is fixedly connected to the outer wall of the block, and a slot is fixedly installed on the surface of the solution chamber on the side of the block. A mounting frame is fixedly installed on the upper outer wall of the solution chamber on the side of the slot, and a trigger switch and an alarm mechanism are respectively installed on the inner and outer walls of the mounting frame.
[0008] Preferably, the limiting mechanism includes a limiting plate, a knob, and a clamping plate, wherein the limiting plate is fixedly installed on the upper surface of the bracket, the inner wall of the limiting plate is movably connected to the knob, and the end of the knob is movably installed with the clamping plate.

[0015] As the salt solution is continuously used, its level gradually decreases, causing the float to move downwards. This, in turn, pulls a rope, causing a block to rise relative to the slot. The block then moves a trigger rod upwards. When the salt solution is nearly depleted, the trigger rod engages with a trigger switch, activating the alarm mechanism. This alarm alerts the user that the salt solution is running low, allowing for timely replenishment and ensuring the device's continued operation. Therefore, the device effectively alerts the user when the salt solution is running low, ensuring the stability of coating testing and enhancing its practicality. Attached Figure Description

[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 1-5 This utility model provides a technical solution: a salt spray tester for coating testing, comprising a base plate 1, a salt spray chamber 2, a solution chamber 3, a cover 4, a support 5, a limiting mechanism 6, a limiting plate 601, a knob 602, a clamping plate 603, a heating mechanism 7, a delivery pump 8, a pipe 9, an atomizing nozzle 10, an end cap 11, a guide wheel 12, a pull rope 13, a float 14, a block 15, a trigger rod 16, a slot 17, a mounting bracket 18, a trigger switch 19, and an alarm mechanism 20. The salt spray chamber 2 and the solution chamber 3 are fixed to both ends of the upper surface of the base plate 1, and the cover 4 is installed on the upper end of the salt spray chamber 2. The support 5 is fixedly connected to the inner wall of the salt spray chamber 2, and the limiting mechanism 6 is installed at equal intervals along the upper edge of the support 5. The lower surface of the solution chamber 3 is provided with… The system includes a heating mechanism 7, and a delivery pump 8 is installed on the side of the upper surface of the solution tank 3. The end of the delivery pump 8 is connected to the atomizing nozzle 10 via a pipe 9. An end cap 11 is threaded onto the inner wall of the solution tank 3 on the side of the delivery pump 8. A guide wheel 12 is provided on the upper surface of the solution tank 3 on the side of the end cap 11. A pull rope 13 is movably connected to the outer wall of the guide wheel 12. A float 14 and a block 15 are fixed to the two ends of the pull rope 13, respectively. A trigger rod 16 is fixedly connected to the outer wall of the side of the block 15. A slot 17 is fixedly installed on the surface of the solution tank 3 on the side of the block 15. A mounting bracket 18 is fixedly installed on the upper outer wall of the solution tank 3 on the side of the slot 17. A trigger switch 19 and an alarm mechanism 20 are respectively installed on the inner and outer walls of the mounting bracket 18.
[0024] The limiting mechanism 6 includes a limiting plate 601, a knob 602, and a clamping plate 603. The limiting plate 601 is fixedly installed on the upper surface of the bracket 5, and the knob 602 is movably connected to the inner wall of the limiting plate 601. The clamping plate 603 is movably installed at the end of the knob 602, so as to facilitate the positioning of the sample on the bracket 5 by the limiting mechanism 6.
[0025] The knob 602 and the limiting plate 601 are threaded together, and the knob 602 and the clamping plate 603 form a rotating structure, which makes it easy for the user to rotate the knob 602 so that the knob 602 moves relative to the limiting plate 601, thereby pushing the clamping plate 603 to move so that the clamping plate 603 fits against the sample to limit the sample.
[0026] Pipe 9 and solution chamber 3 are connected through each other, and solution chamber 3 and atomizing nozzle 10 are fixedly connected. Atomizing nozzle 10 is located inside salt spray chamber 2, so that the salt solution in pipe 9 can be atomized through atomizing nozzle 10 and sprayed into salt spray chamber 2, thereby creating a salt spray environment in salt spray chamber 2.
[0027] The float 14 is located inside the solution tank 3, and the solution tank 3 and the pull rope 13 are slidably arranged. The pull rope 13 and the guide wheel 12 are in contact, so that the float 14 floats on the salt solution in the solution tank 3. As the salt solution decreases with use, the float 14 moves down, thereby driving the pull rope 13 to move.
[0028] The block 15 and the slot 17 form a sliding structure, which allows the float 14 to move downwards and drive the pull rope 13 to pull the block 15 upwards relative to the slot 17.
[0029] The trigger rod 16 and the trigger switch 19 are in contact, and the trigger switch 19 is electrically connected to the alarm mechanism 20. This allows the block 15 to move upward and drive the trigger rod 16 to move, so that the trigger rod 16 is in contact with the trigger switch 19, thereby allowing the trigger switch 19 to activate the alarm mechanism 20. At this time, the device reminds the user that the salt solution is almost used up.
[0030] Working principle: When using this salt spray tester for coating testing, firstly as follows... Figure 1-5As shown, the user inserts the coated sample plate between the support 5 and the clamp 603. Then, the user rotates the knob 602, which moves relative to the limiting plate 601. The knob 602 then moves the clamp 603, causing it to conform to the sample, thus positioning the sample in the salt spray chamber 2. Next, the user closes the chamber lid 4 and pours the salt solution into the solution chamber 3. The user then inserts the end cap 11 into the solution chamber 3 and tightens it. The user then activates the heating mechanism 7, which heats the salt solution in the solution chamber 3. Once the salt solution is heated, the user activates the delivery pump 8, which pumps the heated salt solution through the pipe 9 into the atomizing nozzle 10. The atomizing nozzle 10 then atomizes the hot salt solution and sprays it into the salt spray chamber 2, creating a salt mist environment within the chamber 2. The process involves salt spray testing of the coating. As the salt solution in solution chamber 3 decreases, the salt solution level drops, causing the float 14 floating on the salt solution to move downwards. This float 14 moves the pull rope 13 relative to the guide wheel 12, which in turn pulls the block 15 upwards relative to the slot 17. Simultaneously, the block 15 moves the trigger rod 16 upwards. As the salt solution decreases further, the trigger rod 16 continues to move upwards. When the salt solution is nearly depleted, the trigger rod 16 moves to engage with the trigger switch 19, activating the alarm mechanism 20. This alarm mechanism alerts the user that the salt solution is running low, allowing the user to replenish the salt solution promptly and ensuring the device's normal operation. Therefore, the device effectively alerts the user when the salt solution is running low, ensuring the stability of the coating testing and improving its practicality.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
