[0002] Interior design is divided into residential design, commercial design, and spatial design. Interior design is not just about drawing up the corresponding structure on paper. Staff also need to conduct on-site inspections and simulate the lighting environment to clearly understand the impact of different installation positions of the lights on the lighting effect. The specific installation positions of the lights will change as the house renovation progresses and some layouts are changed. Therefore, multiple simulations of the lighting effect are needed to determine the final installation positions of the lights.

[0030] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual size and shape of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 4As shown, this invention is a lighting environment simulation device for interior design, comprising a base 1, a lifting column 2 fixed on the base 1, a lamp mounting column 3 fixed on the top of the lifting column 2, multiple lamps 4 mounted on both ends of the lamp mounting column 3, and cylindrical protective covers 5 fixed on both ends of the lamp mounting column 3. The protective covers 5 are made of transparent material. Cleaning rings 6 are fitted onto both protective covers 5. Brushes are provided on the sidewalls of the cleaning rings 6 facing the protective covers 5. A first mounting base 7 is mounted on the bottom of the cleaning rings 6. Two support rods 8 are rotatably mounted on the first mounting base 7. Magnetic components 9 are symmetrically arranged on the base 1, with two magnetic components 9 located on both sides of the lifting column 2. Adsorption components 10 are attracted to the magnetic components 9, and a second mounting base 11 is fixed to the adsorption components 10. The two support rods 8 are located away from the first mounting base 7. One end is rotatably connected to the second mounting base 11; when simulating light illumination, place the base 1 in the designated position, and use the lifting column 2 to raise the lamp mounting column 3 to the designated height. When the lamp mounting column 3 is raised, due to the attraction between the magnetic component 9 and the adsorption component 10, the two cleaning rings 6 will approach each other. Use the cleaning rings 6 to clean the surface of the protective cover 5. After the cleaning rings 6 move from one end of the protective cover 5 to the other end, the lamp mounting column 3 continues to rise. At this time, the pulling force is greater than the attraction force between the magnetic component 9 and the adsorption component 10, and the magnetic component 9 and the adsorption component 10 separate. This will not affect the normal rise of the lamp mounting column 3. After rising to the designated position, the lamp 4 can be turned on to simulate the lighting environment. It should be noted that the magnetic component 9 is a magnet, and the adsorption component 10 is made of iron.

[0033] See Figure 1 , Figure 3 and Figure 5 The lifting column 2 has vertical grooves 12 on both sides of its side walls. A slider is slidably connected in the groove 12 and fixedly connected to the adsorption component 10. The bottom of the first mounting base 7 is fixed with a mounting rod 13 and a stop rod 14 is fixed at the bottom of the mounting rod 13. To prevent the support rod 8 from being in a vertical state, the stop rod 14 is provided. When the magnetic component 9 separates from the adsorption component 10, the stop rod 14 supports the support rod 8, so that the support rod 8 still has a certain tilt, which is convenient for resetting.

[0034] See Figure 1 A vertical rod 16 is fixed on the lamp mounting column 3. A horizontal rod 17 is fixed to the top of the vertical rod 16. Moving blocks 15 are slidably connected to both ends of the horizontal rod 17. The two moving blocks 15 are fixedly connected to the two cleaning rings 6 respectively. A first limiting block 18 and a second limiting block 19 are provided at both ends of the horizontal rod 17. The moving blocks 15 are located between the first limiting block 18 and the second limiting block 19. The horizontal rod 17 limits and guides the cleaning rings 6 to facilitate their movement. The first limiting block 18 and the second limiting block 19 limit the stroke of the cleaning rings 6 to prevent them from falling off the horizontal rod 17 or moving too far.

[0035] See Figure 1 , Figure 6 and Figure 7 The lifting column 2 includes an outer cylinder 201 fixed to a base 1, a first inner cylinder 202 movably disposed inside the outer cylinder 201, a second inner cylinder 203 movably disposed inside the first inner cylinder 202, and a third inner cylinder 204 movably disposed inside the second inner cylinder 203. The top of the third inner cylinder 204 is fixedly connected to the lamp mounting column 3. A stop block 206 is provided at the bottom of the outer cylinder 201, the first inner cylinder 202, and the second inner cylinder 203. An opening is provided at the bottom of the first inner cylinder 202, the second inner cylinder 203, and the third inner cylinder 204. Both the bottom of the second inner cylinder 203 and the third inner cylinder 204 are provided with convex rings. The bottom of the outer cylinder 201 is connected to an air inlet pipe 205, one end of which is connected to an external air pump. When it is necessary to raise the lamp mounting column 3, simply use the external air pump to inflate the lifting column 2. Under the action of air pressure, the third inner cylinder 204 gradually rises. When the third inner cylinder 204 moves to the top of the second inner cylinder 203, it drives the second inner cylinder 203 to continue to rise. A one-way valve is installed on the air inlet pipe 205. When the lamp mounting column 3 is raised to the specified height, the air pump can be turned off.

[0036] See Figure 6 and Figure 7 An L-shaped exhaust pipe 207 is connected to the outer cylinder 201, and a solenoid valve 208 is installed on the exhaust pipe 207. After the lighting simulation is completed, the air inside the lifting column 2 can be discharged by opening the solenoid valve 208, and the lifting column 2 will automatically lower and reset.

[0037] See Figures 6 to 8 Two branch pipes 209 are connected to the upper part of the exhaust pipe 207. An L-shaped connecting hole 20 is opened in the magnetic component 9. One end of the two branch pipes 209 is connected to the two connecting holes 20 respectively. A sealing block 21 is fixed at the bottom of the adsorption component 10, and the sealing block 21 matches the size of the connecting hole 20. In order to prevent the lifting column 2 from falling too fast and causing vibration to damage the equipment, after the solenoid valve 208 is opened, the exhaust pipe 207 and the branch pipes 209 exhaust at the same time, so that the lifting column 2 falls quickly. When the adsorption component 10 contacts the magnetic component 9, it means that the lifting column 2 is about to complete the reset. At this time, the sealing block 21 blocks the connecting hole 20, and the air can only be discharged from the exhaust pipe 207, thereby reducing the falling speed of the lifting column 2 in the final stage and reducing the generation of vibration.

[0038] See Figure 1 , Figure 6 and Figure 7One end of the exhaust pipe 207 is provided with a three-way pipe 23, one end of which is fitted onto the exhaust pipe 207. The other two ends of the three-way pipe 23 are connected to multi-stage telescopic pipes 24. Annular pipes 22 are fixed on the sidewalls of the two cleaning rings 6 that are far apart. Multiple nozzles are evenly installed on the side of the annular pipes 22 facing the protective cover 5. The far ends of the two multi-stage telescopic pipes 24 are respectively connected to the two annular pipes 22. When the lifting column 2 descends to the point where the adsorption component 10 contacts the magnetic component 9, the three-way pipe 23 is just fitted onto the exhaust pipe 207. The gas discharged from the exhaust pipe 207 enters the multi-stage telescopic pipe 24 through the three-way pipe 23, and then enters the annular pipe 22 and blows towards the protective cover 5. At this time, under the action of the support rod 8, the cleaning ring 6 gradually returns to its initial position, and with the help of the annular pipe 22, the dust is further removed.

[0039] See Figure 1 , Figure 6 and Figure 9 A fixing block 25 is fixed inside the three-way pipe 23, and a push rod 26 is connected to the bottom of the fixing block 25. A sealing ring 27 is fixed inside the exhaust pipe 207 near the end of the three-way pipe 23. A spring 28 is connected inside the exhaust pipe 207, and a sealing ball 29 is connected to one end of the spring 28. The sealing ball 29 is located below the sealing ring 27. In order to make full use of the air inside the lifting column 2, a spring 28 and a sealing ball 29 are set inside the exhaust pipe 207. When the push rod 26 on the three-way pipe 23 is disengaged from the exhaust pipe 207, the sealing ball 29 contacts the sealing ring 27, preventing the exhaust pipe 207 from venting. Only when the lifting column 2 descends will the push rod 26 push the sealing ball 29 to disengage from the sealing ring 27, allowing air to enter the three-way pipe 23, thereby reducing the waste of air pressure and ensuring the cleaning effect.

[0040] The working principle of this invention is as follows: When simulating light illumination is required, the base 1 is placed in the designated position, and an external air pump (not shown) is used to inflate the lifting column 2. Under the action of air pressure, the third inner cylinder 204 gradually rises. When the third inner cylinder 204 moves to the top of the second inner cylinder 203, it drives the second inner cylinder 203 to continue to rise. When the lamp mounting column 3 rises to the designated height, the air pump can be turned off. In the initial state, the two cleaning rings 6 are located on both sides. When the lamp mounting column 3 rises, due to the adsorption of the magnetic component 9 and the adsorption component 10, the two cleaning rings 6 will move towards the middle. The cleaning rings 6 are used to clean the surface of the protective cover 5. When the cleaning rings 6 move to the first limit block 18, they stop moving, while the lamp mounting column 3 continues to rise. At this time, the pulling force is greater than the adsorption force between the magnetic component 9 and the adsorption component 10, and the magnetic component 9 and the adsorption component 10 separate. This will not affect the normal rise of the lamp mounting column 3. After rising to the designated position, the lamp 4 can be turned on to simulate the lighting environment.

[0041] When the lighting simulation is complete and the lifting column 2 needs to be lowered, the solenoid valve 208 is opened, and gas is discharged through the two branch pipes 209. Initially, the sealing ball 29 is in contact with the sealing ring 27, and the exhaust pipe 207 cannot exhaust gas, allowing the lifting column 2 to descend rapidly. To prevent the first inner cylinder 202, the second inner cylinder 203, and the third inner cylinder 204 from vibrating violently against the base 1 during descent, the adsorption component 10 contacts the magnetic component 9, sealing the connecting hole 20 and reducing the exhaust rate, thereby lowering the first inner cylinder 202, the second inner cylinder 203, and the third inner cylinder 204. The descent speed of the third inner cylinder 204, and at this time the three-way pipe 23 is just fitted onto the exhaust pipe 207, the push rod 26 pushes the sealing ball 29 to disengage from the sealing ring 27, allowing air to enter the three-way pipe 23. The gas discharged from the exhaust pipe 207 enters the multi-stage telescopic pipe 24 through the three-way pipe 23, and then enters the annular pipe 22 and blows towards the protective cover 5. At this time, under the action of the support rod 8, the cleaning ring 6 gradually moves from the middle to both sides, and with the air blown out by the annular pipe 22, further removes the dust, and also causes the lifting column 2 to slowly reset.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
