AI Technical Summary
Existing cyclone teaching aids are unable to realistically simulate three-dimensional cyclones on a flat surface, resulting in poor demonstration effects, poor observational value, and difficulty in helping students understand the shape of cyclones.
A cyclone-forming component was designed, consisting of two relatively offset semi-cylindrical plates, forming a cyclone-forming space. It simulates a cyclone through an airflow channel, uses combustibles to generate flames or smoke, and utilizes the pressure difference to form rotating flames or smoke, thus simulating the natural cyclone phenomenon.
It enables visualization experiments of cyclones, enhancing observation and realism. It is simple to operate and the device is small and portable.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of teaching instrument technology, specifically a visual experimental device for simulating micro cyclones. Background Technology
[0002] A cyclone is a large vortex in the atmosphere of the Northern (Southern) Hemisphere where horizontal airflow rotates counterclockwise (clockwise). At the same altitude, the air pressure at the center of a cyclone is lower than the surrounding areas, hence it is called a low-pressure area. On a contour map, it appears as a low-pressure area enclosed by closed isobars; on an isobaric map, it appears as a low-value area enclosed by closed contour lines. Cyclones are approximately circular or elliptical in shape. Cyclones are the most common form of atmospheric motion and an important weather system affecting weather changes; therefore, cyclones are a key topic in teaching.
[0003] Current cyclone teaching aids are usually two-dimensional demonstrations, using colored light boards to show the direction of cyclone flow. The problem with this type of cyclone teaching aid is that cyclones are three-dimensional weather systems, and the two-dimensional demonstration differs greatly from the actual situation in three-dimensional space. The demonstration effect is far from the real situation, resulting in poor demonstration effect and difficulty in helping students understand. A small number of other teaching aids use a circular tube with a sealed side and open top and bottom, with a fan at the top to achieve the experimental effect. These demonstration methods are difficult to realize a relatively three-dimensional cyclone, and it is also difficult to observe the specific shape of the cyclone. The viewing experience is poor, and there is still room for improvement. Utility Model Content
[0004] The purpose of this invention is to provide a visual experimental device for simulating microcyclones in order to solve the problems mentioned above.
[0005] The technical solution adopted by this utility model is as follows: A visualization experimental device for simulating micro cyclones includes a cyclone forming component and a combustible material. The cyclone forming component includes a top plate and a semi-cylindrical plate installed vertically at the bottom of the top plate. There are two semi-cylindrical plates, which are staggered relative to each other. A cyclone forming space is formed between the two semi-cylindrical plates. Airflow channels connected to the outside are provided on both sides of the cyclone forming space.
[0006] In a preferred embodiment, both the semi-cylindrical plate and the top plate are made of a high-temperature resistant transparent material.
[0007] In a preferred embodiment, a heat-insulating pad is provided at the bottom of the combustible material.
[0008] In a preferred embodiment, the top plate and the semi-cylindrical plate are either an integral structure or separate structures.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: Two relatively staggered semi-cylindrical plates are designed, and the staggered semi-cylindrical plates form two air ducts. The combustible material is placed at the bottom center of the cyclone forming component. When the combustible material is working, flame / smoke is generated. The two air ducts of the outside air form an air pressure difference, resulting in a rotating flame / smoke, i.e., a cyclone. The above method can simulate the experimental effect in nature to the greatest extent, with strong visual appeal. The experimental operation is simple and convenient. At the same time, the product is small and easy to carry. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0015] Example 1:
[0016] Reference Figure 1-2 A visualization experimental device simulating a micro cyclone includes a cyclone-forming component and a combustor 4. The cyclone-forming component includes a top plate 1 and two semi-cylindrical plates 2 vertically installed at the bottom of the top plate 1. The two semi-cylindrical plates 2 are staggered relative to each other, forming a cyclone-forming space between them. Airflow channels 3 connecting to the outside are provided on both sides of the cyclone-forming space. The combustor 4 is placed at the bottom center of the cyclone-forming space. The two staggered semi-cylindrical plates 2 form two airflow channels 3. When the combustor 4 is placed at the bottom center of the cyclone-forming component, flames / smoke are generated. The air in the center is heated and rises, the internal air pressure decreases, and the external airflow enters the cyclone-forming space from the airflow channels 3 and spirals upward, forming a cyclone or fire tornado phenomenon. The above method can simulate the experimental effect of nature to the greatest extent, with strong visual appeal, simple and convenient experimental operation, and the product is small and easy to carry.
[0017] Among them, the combustible material 4 is an object or device that can produce flame / smoke, which may be a metal fuel box or incense burner for storing alcohol or agarwood, and is not limited here.
[0018] In this embodiment, both the semi-cylindrical plate 2 and the top plate 1 are made of high-temperature resistant transparent material, which ensures operational safety while allowing for intuitive observation of the experimental results.
[0019] In this embodiment, a heat insulation pad 5 is provided at the bottom of the combustible material 4. The heat insulation pad 5 can insulate the combustible material 4 from heat. The heat insulation pad 5 is made of heat insulation material, such as asbestos. The heat insulation pad 5 can also be designed as a box that can wrap the combustible material 4. No limitation is made here.
[0020] In this embodiment, the top plate 1 and the semi-cylindrical plate 2 are either an integral structure or a separate structure, which can be selected according to different scenarios. For example, an integral structure can facilitate direct use by the user, while a separate structure can save storage space. When it is a separate structure, the top plate 1 is designed with a slot to accommodate the insertion of the semi-cylindrical plate 2, or it can be directly connected by snap-fit or screw fastening. In addition, a through hole smaller than the diameter of the semi-cylindrical plate 2 is opened in the center of the top plate 1.
[0021] The specific experimental steps are as follows: place the ignited combustion material 4 and the cyclone forming component on a table, and place the combustion material 4 at the bottom center of the cyclone forming component. Place a heat insulation pad 5 under the combustion material 4. The combustion material 4 produces flames / smoke. The air in the center is heated and rises, the internal air pressure decreases, and the external airflow enters the cyclone forming space from the airflow channel 3 and spirals upward, forming a cyclone or fire tornado phenomenon.
[0022] Example 2:
[0023] The difference between Example 2 and Example 1 is that, referring to... Figure 3 As shown, an exhaust device 6 is installed in the through hole of the top plate 1. The exhaust device 6 can be an externally powered exhaust fan. The exhaust device 6 can draw air upward, thereby quickly forming an upward airflow, which can enhance the experimental effect.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
