[0052] The control component 100 is mainly used for people to participate in the operation to achieve control of the display component 200.

[0053] Specifically, the control component 100 includes an operating platform 120 , on which a switch unit 110 for connecting with the display component 200 is disposed.

[0054] The switch part 110 is connected to the display assembly 200 through a control system. The switch part 110 can be configured as a switch or as a sensing structure for sensing human body operation signals.

[0055] In some embodiments of the present application, the operating platform 120 is disposed on the ground, and the switch portion 110 is a pedal key disposed on the operating platform 120 , and the overall structure is similar to a dance mat.

[0056] The operating platform 120 is a platform structure with a length of about 2 meters and a width of about 1 meter. The experiencer stands on the operating platform 120 and steps on the switch part 110 with his feet to control the display component 200.

[0057] The display assembly 200 includes a support platform 210 , an air outlet base 220 and a protective cover body 230 . The support platform 210 provides a supporting foundation for the entire display assembly 200 .

[0058] The overall height of the display assembly 200 is about 2.7 meters, the height of the support platform is about 0.6 meters, the overall height of the protective cover is about 2 meters, and the length is about 1.5 meters. The large-size structure of the display assembly 200 is conducive to convenient observation by the experiencer and improves the realism of the snowflake demonstration.

[0059] refer to Figure 2 , Figure 8 as well as Fig. 9 At least one fan 212 is disposed in the support platform 210 , and at least one air outlet area is formed on the air outlet base 220 , and the air outlet area includes at least one air outlet portion 221 connected to the air outlet end of the fan 212 .

[0060] The material of the protective cover body 230 is tempered glass, which is safe and convenient for observation.

[0061] The protective cover body 230 is covered on the air outlet base 220 , and a display inner cavity for accommodating the floating element is formed between the protective cover body 230 and the air outlet base 220 .

[0062] Each protective cover body 230 is formed with an exhaust port to achieve airflow in the display cavity.

[0063] The exhaust port may be disposed on a side wall of the protective cover body 230 , or may be disposed on a top of the protective cover body 230 .

[0064] refer to Figure 4 , Figure 5The switch part 110 controls the opening of the fan 212 through the control system. When people step on the switch part 110, the fan 212 connected thereto is turned on, and the airflow output by the fan 212 is transported to the display cavity through the air outlet, blowing the floating parts located in the display cavity upward.

[0065] The floating parts are such as foam sheets, foam balls or even paper pieces, and the fan 212 provides wind force from bottom to top for the floating parts, simulating the left and right swinging and up and down flying effects of snowflakes under the natural wind force, which is very vivid.

[0066] In order to enable multiple people to participate together and increase the fun, the display component 200 of the present application is divided into multiple areas.

[0067] A plurality of fans 212 are arranged in the support platform 210 , a plurality of air outlet areas corresponding to the air outlet ends of the fans 212 are arranged on the air outlet base 220 , and a plurality of switch parts 110 for controlling the switches of the fans 212 are arranged on the operating platform 120 .

[0068] Correspondingly, the display inner cavity in the protective cover body 230 is divided into a plurality of display areas corresponding to each air outlet area by vertically arranged baffles.

[0069] Combination Figure 1 , Figure 8 Six air outlet areas a, b, c, d, e, and f are formed on the air outlet base 220. A vertically upward blocking member 231 is provided on the air outlet base 220. The blocking member 231 also divides the display inner cavity in the protective cover body 230 into six corresponding display areas.

[0070] Corresponding to the six air outlet areas on the air outlet base 220, six fans 212 are installed in the support platform 210. The input end of each fan 212 is connected to the outside, and the output end is connected to the air outlet parts 221 in the six air outlet areas respectively.

[0071] Each air outlet area includes a plurality of air outlet portions 221 arranged in an array. The air outlet portions 221 are specifically a through-hole structure, which realizes the conveyance of airflow from bottom to top.

[0072] For the convenience of processing, each air outlet area in the air outlet base 220 can be manufactured separately and then assembled into one.

[0073] In order to prevent the floating parts from falling from the air outlet 221 to the outside of the display cavity, a mesh cover is fixed on the surface of the air outlet 221, and each cover is detachably mounted on the air outlet 221 by means of fastening screws and other structures.

[0074] There are many ways to connect the fan 212 with the air outlet portion 221 in each air outlet area, for example but not limited to, the bottom of the support platform 210 is divided into six air supply chambers 211 corresponding to each air outlet area, and each air supply chamber 211 is connected to the output end of the corresponding fan 212.

[0075] Each fan 212 is connected to a corresponding switch unit 110 .

[0076] On the operating platform 120 , six control areas A, B, C, D, E, and F are provided corresponding to each air outlet area, and a switch unit 110 for controlling the corresponding fan 212 is provided in each control area.

[0077] The experiencer steps on the switch 110 to turn on the fan 212 in the corresponding air outlet area, and delivers the airflow to the corresponding area of ​​the display cavity through each air outlet 221 in the air outlet area, blowing up the floating objects in the area.

[0078] When multiple people step on the switch parts 110 at different positions at the same time, multiple fans 212 can be turned on at the same time to form different display effects.

[0079] The setting of the control area and the air outlet area is not limited to the above-mentioned specific zoning method, and different numbers can be set according to the actual site size.

[0080] In some embodiments of the present application, the top of the protective cover body 230 is an open structure.

[0081] refer to Figure 1 , Figure 2 In order to avoid excessive wind force, the floating member is blown out from above the protective cover body 230 , a cover member 240 is provided on the top of the protective cover body 230 , and an exhaust port is formed on the cover member 240 .

[0082] It should be noted that at least one exhaust vent needs to be provided above each area in the display cavity.

[0083] In other embodiments, in order to improve the display effect, a light-emitting member 241 is further provided on the cover member 240 above the corresponding display area.

[0084] There is at least one light emitting member 241 above each display area.

[0085] The light emitting element 241 can emit lights of different colors according to the control signal to enhance the effect of snowflakes flying.

[0086] For example but not limited to, two switch units 110 are respectively provided in the six control areas A, B, C, D, E, and F.

[0087] The corresponding switch parts 110 in each area are all connected to the fan 212, but different switch parts 110 correspond to different lighting effects.

[0088] That is, each switch unit 110 can control the corresponding fan 212 to turn on and at the same time, specifically control the light-emitting element 241 above the corresponding display area to emit lights of different colors.

[0089] For a more convenient experience, a color label is attached to each switch portion 110 .

[0090] For example, white and yellow labels are respectively affixed to the two switch parts 110 in the A control area. Then, the light-emitting part 241 corresponding to the top of the a air outlet area can emit white light when the experiencer triggers the white switch part 110, and emit yellow light when the yellow switch part 110 is triggered.

[0091] Then, while the corresponding area is formed with the effect of flying snowflakes, there is also a lighting effect, which makes the visual more beautiful.

[0092] refer to Figure 5 , Figure 6 The switch unit 110 is detachably connected to the operating platform 120. Specifically, a downwardly extending mounting recess is formed in each control area of ​​the operating platform 120, and the switch unit 110 is fixed in the corresponding mounting recess through a support frame.

[0093] The support frame specifically includes a positioning sleeve 111 , and the positioning sleeve 111 is in a circular, square or other shape.

[0094] A bottom supporting portion 112 is formed at the bottom of the positioning sleeve 111 , and the switch unit 110 is installed in the bottom supporting portion 112 .

[0095] Specifically, the switch portion 110 includes a pressure sensor 114 and a buffer pad 115 . The pressure sensor 114 is specifically in the shape of a thin sheet and is attached to the surface of the bottom support portion 112 .

[0096] The buffer pad 115 is made of a silicone pad, and the buffer pad 115 is connected to the positioning sleeve 111 in a tight fit manner.

[0097] The experiencer steps on the cushion 115 , and the pressure is transmitted to the pressure sensor 114 through the cushion 115 , and the control signal is transmitted to the corresponding fan 212 through the control system.

[0098] The pressure sensor 114 is installed at the bottom of the positioning sleeve 111, and the buffer pad 115 is arranged above the pressure sensor 114. The pressure sensor 114 is connected to the corresponding fan 212 and the light-emitting component 241 through the control system. The pressure sensor 114 is configured to control the start and stop of the corresponding fan 212 and the light-emitting component 241 when the pressure is sensed.

[0099] When the experiencer releases the buffer pad 115 and the pressure transmitted to the pressure sensor 114 decreases, the control system controls the corresponding fan 212 to shut down.

[0100] The control system adopts a PLC signal acquisition system to collect the instantaneous trigger signal of the pressure sensor 114 to control the start and stop of the fan 212. At the same time, delay control is retained according to the actual effect (the control time is adjustable), and a return air system is added to the closed space to ensure the internal air flow effect, form a fixed air flow channel, and guide the movement of the foam balls to achieve controllable shape.

[0101] The upper portion of the positioning sleeve 111 is detachably connected to the operating platform 120 via an annular crimping portion 113 .

[0102] In some embodiments, the crimping portion 113 is a structure of a connecting outer edge formed above the positioning sleeve 111 and extending outward, and is integrally formed with the positioning sleeve 111. At least one fixing hole is provided on the crimping portion 113, and is fixed to the operating platform 120 by fasteners such as fastening bolts 121.

[0103] refer to Figure 7 In other embodiments, the crimping portion 113 and the positioning sleeve 111 are manufactured separately, and the crimping portion 113 is an annular pressure plate structure. The inner edge size of the crimping portion 113 is smaller than the inner diameter of the positioning sleeve 111, and the outer edge size of the crimping portion 113 is larger than the inner diameter of the positioning sleeve 111.

[0104] After the positioning sleeve 111 is installed, the crimping portion 113 is coaxially connected to the top of the positioning sleeve 111 and fixed to the operating platform 120 via fasteners.

[0105] At the same time, the inner side of the crimping portion 113 is also partially crimped onto the buffer pad 115 , further fixing the buffer pad 115 in the positioning sleeve 111 .

[0106] The control system is installed inside the support platform 210. The support platform 210 includes a frame assembly and an outer shell covering the outer side of the frame assembly.

[0107] The overall frame assembly is made of steel frames connected in a horizontal and vertical manner, and the outer shell is made of flame-retardant material to improve safety.

[0108] refer to Fig.10 In order to facilitate maintenance, an inspection door 213 is provided on the outer shell to facilitate the staff to inspect the working parts inside.

[0109] The fan 212 can be directly installed on the outer shell, or can be arranged inside the outer shell and communicated with the outside through an air inlet pipeline.

[0110] The snowflake demonstration interactive system involved in the present application includes a display component 200 and a control component 100. The switch unit 110 in the control component 100 is used to control the fan 212 at the corresponding position to turn on, so as to deliver the airflow to the air outlet 221 of the corresponding air outlet area, and blow up the floating member above the air outlet 221. The floating member can simulate the effect of snowflakes swinging left and right and flying up and down under the driving force of the wind from bottom to top, which is very vivid.

[0111] The floating objects are always enclosed in the display cavity and will not come into direct contact with the experiencers. Hygiene and safety are greatly improved, and the hidden dangers of bacterial infection caused by multiple people touching the floating objects are effectively avoided.

[0112] The display component 200 and the control component 100 are provided with a plurality of control and display areas, which can realize simultaneous control by multiple persons, realize multi-person participation experience, and increase the fun.

[0113] This application combines the process of snowflakes flying with lighting effects to better enhance the visual effect.

[0114] In addition, the process of the experiencer controlling the flying snowflakes is conducive to improving interactivity, stimulating people's interest in observation, and increasing scientific popularization.

[0115] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
