Description

Technical Field

[0001] This invention relates to the field of demonstration device technology, specifically a three-dimensional model interactive demonstration device. Background Technology

[0002] In the field of interactive 3D model demonstrations, glass covers are crucial components that protect models from external interference, and the cleanliness of their surfaces directly impacts the viewer's visual experience. Traditional glass cover cleaning methods largely rely on manual operation, which is not only inefficient and unable to guarantee uniformity and thoroughness, but also makes it difficult to effectively collect and dispose of the dust and stains generated during cleaning, potentially causing secondary pollution to the surrounding environment.

[0003] Especially in educational institutions such as schools and training institutions, 3D model interactive demonstration devices are used for teaching demonstrations and scientific research experiments. Students need to clearly observe the details of the model to understand abstract knowledge and concepts. However, traditional manual cleaning methods may affect the normal teaching progress due to improper cleaning time arrangements, and may also fail to clean the stains on the glass cover surface in time, interfering with students' observation of the model and thus reducing the teaching effect.

[0004] Based on this, a three-dimensional model interactive demonstration device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional model interactive demonstration device to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A three-dimensional model interactive demonstration device includes a base box, which has a bottom cavity and a top cavity opened from top to bottom. The front and rear ends of the base box are hinged with doors, and a display structure is provided inside the bottom cavity.

[0008] The display structure includes a motor installed inside a cavity. The output of the motor is fixedly connected to a drive gear, which meshes with a driven gear. A multi-stage telescopic rod is fixed to the upper end of the driven gear. A placement seat for placing the model is fixed to the telescopic end of the multi-stage telescopic rod. A glass cover is provided outside the placement seat. The glass cover rotates with the base box. The bottom end of the glass cover is connected to a cleaning structure. Sensor probes are symmetrically installed on both sides of the front end of the base box. The sensor probes are electrically connected to a controller. The controller is installed on the right end of the base box and is electrically connected to the motor and the multi-stage telescopic rod.

[0009] Preferably, the cleaning structure includes a second motor installed inside the bottom cavity, the second motor being electrically connected to a controller, the output end of the second motor extending into the top cavity and fixedly connected to a second drive gear, the second drive gear meshing with a second driven gear, the second driven gear rotating with the placement seat, a glass cover fixed to the upper end of the second driven gear, an arc block provided behind the glass cover, the arc block being fixed to the upper end of the bottom box, a rubber scraper fixed to the end of the arc block near the glass cover and conforming to the outer wall of the glass cover, and a dust collection structure provided inside the bottom cavity.

[0010] Preferably, the dust collection structure includes a suction port, which is located at one end of the arc block near the glass cover. The suction port is located to the right of the rubber scraper. A suction pipe is installed at the lower end of the arc block. The suction port is connected to one end of an S-shaped tube via the suction pipe. The other end of the S-shaped tube extends into the dust collection tank to fix a dust discharge pipe. A one-way air valve is installed inside the S-shaped tube. The dust collection tank is connected to the inside of a bent tube via an air pipe. The bent tube is fixed to the upper end of the bottom box. The air pipe's opening inside the dust collection tank is higher than the connection point between the S-shaped tube and the dust discharge pipe. The bottom end of the bent tube extends into the top cavity and rotates with the driven gear three. The driven gear three meshes with the driven gear two. A fan is fixedly connected to the upper end of the driven gear three via a fixing rod. The fan is located inside the bent tube. A filter plate is installed at the other end of the bent tube.

[0011] Preferably, a limiting ring one is fixed to the outer wall of the S-shaped tube, and a sensor is provided at the bottom end of the limiting ring one. A limiting ring two is fixed to the outer wall of the bottom end of the dust discharge pipe. A filter cover is provided between the limiting ring one and the limiting ring two. A fixing cylinder is fixed to the upper end of the filter cover. The inner walls of the filter cover and the fixing cylinder slide against the outer walls of the S-shaped tube and the dust discharge pipe. A fixing ring is fixed to the top of the outer wall of the fixing cylinder. The fixing ring matches the limiting ring one. A bottom ring is fixed to the bottom end of the filter cover. The bottom ring fits against the inner wall of the dust collection tank. Several filter holes are opened through the side wall of the filter cover. The filter holes only allow gas to pass through.

[0012] Preferably, the lower end of the dust collection tank is connected to the interior of the wastewater tank via a wastewater pipe, and a valve is installed on the wastewater pipe. The interior of the dust collection tank is connected to the interior of the water storage tank via a connecting pipe, and a water pump is installed on the connecting pipe. The water pump is electrically connected to the sensor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention combines a cleaning structure with a dust collection structure. Motor 2 drives the glass cover to rotate, while a rubber scraper closely adheres to the outer wall of the glass cover, effectively removing dust and stains. As the glass cover rotates, driven gear 3 rotates along with driven gear 2, causing the fan to generate suction inside the curved tube. This draws dust into the suction port, through the suction pipe into the S-shaped tube, and then into the dust collection tank due to the one-way exhaust valve. This not only ensures the cleanliness of the glass cover surface, facilitating viewing of the model inside, but also effectively prevents dust backflow and leakage, ensuring the efficiency and safety of the dust collection process. Simultaneously, it ensures that people can always clearly observe the model details without being disturbed by dirt.

[0015] 2. This invention utilizes a fan, filter cover, sensor, water pump, and valve in conjunction. The powerful suction generated by the fan inside the curved pipe, combined with the suction port and suction pipe, quickly draws dust and dirt from the glass cover into the dust collection tank. The filter cover effectively filters the inhaled dust and dirt, preventing secondary pollution of the environment by fine particles and ensuring dust collection efficiency. Over time, dust gradually accumulates inside the filter cover, causing the filter pores to become clogged. When the suction force of the fan pulls the clogged filter cover up to the point where the fixed ring contacts the sensor on the limit ring, the sensor immediately sends a signal to the water pump, instructing it to start operating. The water pump then injects cleaning water into the dust collection tank through the connecting pipe to clean the filter cover. After the cleaning process is completed, the sensor sends a stop signal to the water pump again, instructing it to stop operating. At the same time, the valve is automatically opened, allowing the wastewater in the dust collection tank to be smoothly discharged into the wastewater tank through the wastewater pipe, thus completing the entire cleaning and drainage process.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-6 As shown, a three-dimensional model interactive demonstration device includes a base box 1, which has a bottom cavity 12 and a top cavity 13 opened from top to bottom. Box doors 11 are hinged to both the front and rear ends of the base box 1, and a display structure 2 is provided inside the bottom cavity 12.

[0025] The display structure 2 includes a motor 21 installed inside the base cavity 12. The output of the motor 21 is fixedly connected to a drive gear 22. The drive gear 22 meshes with a driven gear 23. A multi-stage telescopic rod 24 is fixed to the upper end of the driven gear 23. A placement seat 25 for placing the model is fixed to the telescopic end of the multi-stage telescopic rod 24. A glass cover 16 is provided outside the placement seat 25. The glass cover 16 rotates with the base box 1. The bottom end of the glass cover 16 is connected to the cleaning structure 3. Sensor probes 15 are symmetrically installed on both sides of the front end of the base box 1. The sensor probes 15 are electrically connected to a controller 14. The controller 14 is installed at the right end of the base box 1 and is electrically connected to the motor 21 and the multi-stage telescopic rod 24.

[0026] In this embodiment, the device is in an inactive state, the door 11 of the base box 1 is closed, and the glass cover 16 covers the placement base 25 and the model on it, protecting the model from external interference. The multi-stage telescopic rod 24 is at its initial length, and the model is securely placed on the placement base 25.

[0027] When displaying the device, the multi-stage telescopic rod 24 adjusts the height of the placement base 25 and the upper model until the model enters the glass cover 16.

[0028] When an audience approaches the device, the sensor 15 detects the signal and sends it to the controller 14. The controller 14 controls the motor 21 to start according to the preset program, which drives the drive gear 22 to rotate, thereby driving the driven gear 23 to move, and further driving the placement base 25 and the upper model to rotate, thus displaying the three-dimensional model from all directions and improving the interactive effect.

[0029] In an optional embodiment, the cleaning structure 3 includes a second motor 31 installed inside the bottom cavity 12. The second motor 31 is electrically connected to the controller 14. The output end of the second motor 31 extends into the top cavity 13 and is fixedly connected to a second drive gear 32. The second drive gear 32 meshes with a second driven gear 33. The second driven gear 33 rotates with the placement seat 25. A glass cover 16 is fixed to the upper end of the second driven gear 33. An arc block 17 is provided behind the glass cover 16. The arc block 17 is fixed to the upper end of the bottom box 1. A rubber scraper 18 that fits against the outer wall of the glass cover 16 is fixed to one end of the arc block 17 near the glass cover 16. A dust collection structure 4 is provided inside the bottom cavity 12.

[0030] It should be noted that the controller 14 can control the start and stop of the second motor 31. When the second motor 31 starts, it drives the second drive gear 32 to rotate, and the second drive gear 32 meshes with the second driven gear 33. Therefore, when the second drive gear 32 rotates, it drives the second driven gear 33 to rotate, and the second driven gear 33 drives the glass cover 16 to rotate. When the glass cover 16 rotates, the rubber scraper 18 scrapes away dust or stains on the outer wall of the glass cover 16.

[0031] In an optional embodiment, the dust collection structure 4 includes a suction port 401, which is located at one end of the arc block 17 near the glass cover 16. The suction port 401 is situated to the right of the rubber scraper 18. A suction pipe 402 is installed at the lower end of the arc block 17. The suction port 401 is connected to one end of an S-shaped tube 403 via the suction pipe 402. The other end of the S-shaped tube 403 extends into the dust collection tank 404, where a dust discharge pipe 405 is fixed. A one-way air outlet valve 408 is installed inside the S-shaped tube 403. An air pipe 41 connects to the inside of the dust collection tank 404. The air pipe 410 is connected to the inside of the bend pipe 411, which is fixed to the upper end of the bottom box 1. The opening of the air pipe 410 inside the dust collection tank 404 is higher than the connection position between the S-shaped pipe 403 and the dust discharge pipe 405. The bottom end of the bend pipe 411 extends into the top cavity 13 and rotates with the driven gear 3 413. The driven gear 3 413 meshes with the driven gear 2 33. The upper end of the driven gear 3 413 is fixedly connected to the fan 415 through the fixing rod 414. The fan 415 is located inside the bend pipe 411. The other end of the bend pipe 411 is equipped with a filter plate 412.

[0032] It should be noted that when the glass cover 16 rotates and drives the rubber scraper 18 to scrape away the dust on the outer wall, the driven gear 3 413 rotates with the driven gear 2 33, driving the fan 415 to generate suction inside the curved tube 411. The suction of the fan 415 acts on the inside of the dust collection tank 404 through the air pipe 410, which causes the dust to be sucked in by the suction port 401. The dust enters the S-shaped tube 403 through the suction pipe 402, and enters the dust collection tank 404 in one direction due to the action of the one-way air outlet valve 408. The filtered air is discharged through the filter plate 412 to prevent dust from re-entering the bottom box 1 or causing pollution to the environment.

[0033] The S-shaped tube 403 and the one-way exhaust valve 408 are designed to reduce dust backflow and improve dust collection efficiency.

[0034] In an optional embodiment, a limiting ring 406 is fixed to the outer wall of the S-shaped tube 403, and a sensor 407 is provided at the bottom end of the limiting ring 406. A limiting ring 409 is fixed to the outer wall of the bottom end of the dust discharge pipe 405. A filter cover 5 is provided between the limiting ring 406 and the limiting ring 409. A fixing cylinder 53 is fixed to the upper end of the filter cover 5. The inner walls of the filter cover 5 and the fixing cylinder 53 slide against the outer walls of the S-shaped tube 403 and the dust discharge pipe 405. A fixing ring 54 is fixed to the top of the outer wall of the fixing cylinder 53. The fixing ring 54 matches the limiting ring 406. A bottom ring 52 is fixed to the bottom end of the filter cover 5. The bottom ring 52 fits against the inner wall of the dust collection tank 404. A plurality of filter holes 51 are provided through the side wall of the filter cover 5. The filter holes 51 only allow gas to pass through.

[0035] It should be noted that when the dust collection structure 4 is working, the gas discharged from the S-shaped tube 403 and a small amount of dust particles enter the filter cover 5. Due to the size limitation of the filter holes 51, only gas can pass through the filter holes 51 into the internal space of the dust collection tank 404, while the dust particles are blocked inside the filter cover 5.

[0036] In an optional embodiment, the lower end of the dust collection tank 404 is connected to the interior of the wastewater tank 6 via a wastewater pipe 61. A valve 62 is installed on the wastewater pipe 61. The interior of the dust collection tank 404 is connected to the interior of the water storage tank 7 via a connecting pipe 71. A water pump 72 is installed on the connecting pipe 71. The water pump 72 is electrically connected to the sensor 407.

[0037] It should be noted that over time, a certain amount of dust will accumulate inside the filter cover 5, clogging the filter holes 51. The suction force of the fan 415 will pull the clogged filter cover 5 upwards until the fixing ring 54 contacts the sensor 407 at the bottom of the limit ring 406. A signal will then be sent to the water pump 72, instructing it to start operating. The water pump 72 will then supply cleaning water to the dust collection tank 404 through the connecting pipe 71. After cleaning is complete, the sensor 407 may send another signal to the water pump 72, instructing it to stop operating. Simultaneously, the valve 62 is opened, allowing wastewater in the dust collection tank 404 to drain into the wastewater tank 6 through the wastewater pipe 61.

[0038] The above embodiment discloses a three-dimensional model interactive demonstration device, wherein when the device is not activated, the door 11 is closed to protect the model from external interference. The multi-stage telescopic rod 24 is at its initial length, stably supporting the placement base 25 and the model on it.

[0039] The multi-stage telescopic rod 24 adjusts the height of the placement base 25 and the model until the model enters the glass enclosure 16. When the audience approaches the device, the sensor 15 detects a signal and sends it to the controller 14. The controller 14 starts the motor 21 according to the preset program, which drives the drive gear 22 to rotate, thereby driving the driven gear 23 and the placement base 25 to rotate, displaying the three-dimensional model from all angles.

[0040] Controller 14 starts motor 31, which drives drive gear 32 to rotate. Drive gear 32 meshes with driven gear 33, driving glass cover 16 to rotate. When glass cover 16 rotates, rubber scraper 18 adheres to the outer wall of glass cover 16, scraping away dust or stains.

[0041] At the same time, as the glass cover 16 rotates, the driven gear 3 413 rotates with the driven gear 2 33, driving the fan 415 to generate suction inside the curved tube 411. This causes dust to be sucked in by the suction port 401, enters the S-shaped tube 403 through the suction pipe 402, and enters the dust collection tank 404 in one direction due to the action of the one-way exhaust valve 408.

[0042] The filtered air is discharged through filter plate 412 to prevent dust from re-entering the bottom chamber 1 or causing environmental pollution.

[0043] Over time, dust accumulates inside the filter cover 5, clogging the filter holes 51. The suction force of the fan 415 pulls the clogged filter cover 5 upwards until the retaining ring 54 contacts the sensor 407 at the bottom of the limiting ring 406. The sensor 407 sends a signal to the water pump 72, instructing it to start working. The water pump 72 supplies cleaning water to the dust collection tank 404 through the connecting pipe 71. After cleaning is completed, the sensor 407 sends a signal to the water pump 72 again, instructing it to stop working. At the same time, the valve 62 is opened, allowing the wastewater in the dust collection tank 404 to be discharged into the wastewater tank 6 through the wastewater pipe 61.

[0044] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
