DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 5 The spray aerosol closed space tester with high temperature simulation function needs to accurately simulate the performance of spray aerosol in different environments, especially the characteristics in high temperature and complex dynamic environment in the research and development and quality detection process of spray aerosol. The traditional tester is difficult to fully meet these needs, and the spray aerosol closed space tester with high temperature simulation function of the embodiment aims to solve these problems and provide more accurate and comprehensive test conditions.

[0030] The fixed assembly 1 is fixedly installed with a limit seat 101 near the middle of the top of both sides, used for supporting and positioning the heating rotator 401, to ensure the stability and accuracy of the heating rotator 401 in the rotating process.

[0031] The aerosol tank fixing assembly 2 is provided with a fixed groove 201 in the middle position of the left side wall, used for placing the aerosol tank body 6, and the inner side wall of the fixed groove 201 is fixedly installed with an air cylinder 202 near the four corner positions, and the output end of the four air cylinders 202 is connected with an arc clamp 203.

[0032] The test instrument body 3 is provided with a sealing cover plate 301 on the right side wall, and a lock hole 302 is formed in the middle position of the left side wall of the sealing cover plate 301, which is used for cooperating with the lock head 407 of the heating assembly 4 to realize the rotary locking of the test instrument body 3 under certain conditions.

[0033] The heating assembly 4 comprises a heating rotator 401, and the test instrument body 3 is movably connected to the middle position of the inner wall of the heating rotator 401.

[0034] A plurality of driven rods 405 are connected to the left side wall of the heating rotator 401, and the other end of each driven rod 405 is fixedly connected to a planetary gear assembly 404. The middle position of the right side wall of the planetary gear assembly 404 is movably connected to a fixed disc 403, and the middle position of the right side wall of the fixed disc 403 is provided with a speed reducer motor 402. The output end of the speed reducer motor 402 is connected to the input end of the planetary gear assembly 404. The left side wall of the planetary gear assembly 404 is fixedly connected to a connecting rod 408 near the middle position, and the other end of the connecting rod 408 is fixedly provided with an electric cylinder 406. The output end of the electric cylinder 406 is connected to a lock head 407.

[0035] The control panel 5 is installed in the middle position of the front side wall of the aerosol tank fixing assembly 2 and is electrically connected to the heating rotator 401, the air cylinder 202, the speed reducer motor 402 and the electric cylinder 406 respectively, for controlling the operation of each component.

[0036] The aerosol tank body 6 is carefully placed in the fixing groove 201 of the aerosol tank fixing assembly 2. The air cylinder 202 is started through the control panel 5, and the four air cylinders 202 work synchronously. The output end drives the arc-shaped clamp 203 to move stably to the center until the arc-shaped clamp 203 tightly fits the outer wall of the aerosol tank body 6, so as to realize the stable clamping and fixing of the aerosol tank body 6, and ensure the stability of the position of the aerosol tank during the subsequent test process, and the sealing cover plate 301 of the test instrument body 3 is closed. The speed reducer motor 402 in the heating assembly 4 is started through the control panel 5. The speed reducer motor 402 starts to work and transmits power to the planetary gear assembly 404. After receiving the power, the planetary gear assembly 404 starts to work. On the one hand, the electric cylinder 406 and the lock head 407 are driven to make circular motion around the central axis of the planetary gear assembly 404 through the connecting rod 408; on the other hand, the planetary gear assembly 404 cooperates with the plurality of driven rods 405 to drive the heating rotator 401 to rotate around the test instrument body 3. The heating rotator 401 gradually heats the test instrument body 3 during the rotation process. The heating temperature of the heating rotator 401 can be accurately set through the control panel 5, so as to simulate different temperature environments

[0037] When it is necessary to simulate the special scene of aerosol in an industrial environment with complex rotating mechanical structure, and the surrounding heat source and the direction of object movement are opposite: start the electric cylinder 406 through the control panel 5, the output end of the electric cylinder 406 acts on the lock head 407 to extend to the end close to the lock hole 302 until the lock head 407 is accurately engaged with the lock hole 302. At this time, the test instrument body 3 starts to rotate under the cooperation of the planetary gear assembly 404 and other components, and the rotating direction is opposite to that of the heating rotator 401, so as to more truly simulate this special complex environment and provide more actual conditions for aerosol performance test.

[0038] When it is not necessary to simulate the special scene, the electric cylinder 406 remains in the unstarted state, the test instrument body 3 does not rotate, and only the heating rotator 401 rotates around the test instrument body 3 for heating and environment simulation.

[0039] During the test, the rotation speed and heating temperature of the heating rotator 401 and the clamping force of the air cylinder 202 on the aerosol can body 6 can be flexibly controlled according to the specific test requirements through the control panel 5. For example, when the performance of aerosol in a high-temperature high-speed airflow environment is studied, the rotation speed and heating temperature of the heating rotator 401 can be increased while ensuring the stable clamping of the aerosol can body 6. Various sensors such as temperature sensors, pressure sensors, and light-sensitive sensors are arranged inside the test instrument body 3, which are not shown in detail in the figure, for collecting various data during the test, such as temperature change, pressure change, and light intensity change during combustion after aerosol spraying. These data are transmitted to the data acquisition system connected thereto for recording and analysis, providing a basis for evaluating the performance of aerosol.

[0040] When the test is completed, the operation of the heating assembly 4 is first stopped through the control panel 5, including the stop of the speed reducer motor 402 and the stop of the heating of the heating rotator 401, and then the output end of the air cylinder 202 drives the arc-shaped clamp 203 to move away from the aerosol can body 6 to release the clamping of the aerosol can body 6, so as to take out the aerosol can body 6.

[0041] If the electric cylinder 406 is started during the test to simulate the special scene, at this time, the output end of the electric cylinder 406 drives the lock head 407 to exit from the lock hole 302 through the control panel 5, and returns to the initial position, and finally the sealing cover plate 301 of the test instrument body 3 is opened for cleaning and inspection of the inside of the test instrument, preparing for the next test operation.

[0042] Through the operation of the above embodiment, the spray aerosol closed space tester with high temperature simulation function can effectively test the performance of spray aerosols in a closed space in multiple aspects, and can simulate various environmental conditions according to different needs, providing reliable test data and condition guarantee for the research and quality detection of spray aerosols, greatly improving the accuracy and comprehensiveness of spray aerosol performance testing.

[0043] Working principle: when the test is needed, first place the aerosol can body 6 in the fixing groove 201 of the aerosol can fixing assembly 2, start the air cylinder 202 through the control panel 5, the output end of the four air cylinders 202 drives the arc-shaped clamp 203 to move to the center, thereby stably clamping and fixing the aerosol can body 6, start the reduction motor 402 in the heating assembly 4 through the control panel 5, the output end of the reduction motor 402 drives the planetary gear assembly 404 to operate. During the operation of the planetary gear assembly 404, on the one hand, the connecting rod 408 drives the electric cylinder 406 and the lock head 407 to make circular motion around the center axis of the planetary gear assembly 404; on the other hand, the planetary gear assembly 404 cooperates with the plurality of driven rods 405 to drive the heating rotator 401 to rotate around the tester body 3. The heating rotator 401 heats the tester body 3 during rotation, thereby simulating different temperature environments. When simulating some special actual scenes, such as simulating the performance of aerosols in some industrial environments with complex rotating mechanical structures, the output end of the electric cylinder 406 acts on the lock head 407 to extend to the end near the lock hole 302, until the lock head 407 is clamped with the lock hole 302, so that the tester body 3 rotates, and the movement direction of the surrounding heat source and object may be opposite. At this time, the reverse rotation of the tester and the rotating drum helps to more realistically simulate this special complex environment, and provides more practical conditions for aerosol performance testing. When it is not necessary to simulate special actual scenes, the electric cylinder 406 is not started at this time, and during the test, the rotation speed, heating temperature and other parameters of the heating rotator 401 can be controlled by the control panel 5, and the clamping force of the air cylinder 202 on the aerosol can body 6 can be controlled. When the test is completed, operate the control panel 5 to restore each part to the initial state for the next test operation.

[0044] The tester can test the performance of spray aerosols in a closed space in multiple aspects, and can simulate different environmental conditions, providing reliable test data and condition guarantee for the research and quality detection of spray aerosols.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
