[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0029] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0030] See also Figure 1-4 The embodiment of the present application provides a continuous instantaneous cold flame eruption device, comprising a feeding structure 1, a conveying and heating structure 2, a spraying structure 3 and a continuous instantaneous jet structure 4. The feeding structure 1 is arranged above the conveying and heating structure 2, the discharge port of the conveying and heating structure 2 is connected to the middle position of the spraying structure 3, the continuous instantaneous jet structure 4 is connected to one end of the spraying structure 3, the feeding structure 1 is used to provide metal powder to the conveying and heating structure 2, the conveying and heating structure 2 is used to convey, heat, ignite and convey the metal powder to the middle position of the spraying structure 3, and the continuous instantaneous jet structure 4 instantly ejects the ignited metal powder located in the spraying structure 3. By setting up the continuous instantaneous jet structure 4, the metal powder is ejected instantly and multiple times, the time interval is short, and there is no need to wait too much time, which gives people a better audio-visual experience and is conducive to better setting off the stage atmosphere.

[0031] Preferably, the spray structure 3 is a cylindrical structure, with the continuous instantaneous jet structure 4 connected to one end thereof, and the other end being a free end, i.e., the end from which the cold flame is emitted, having the advantages of simple structure and easy maintenance; the spray structure 3 is also externally connected to an air pump 25 for supplying oxygen and assisting combustion to the ignited metal powder that falls into the spray structure 3, or combustion can also be achieved by connecting a fan.

[0032] See also Figure 2-3At least two feeding structures 1 and conveying and heating structures 2 are respectively provided. In the present application, two are provided. A conveying and heating structure 2 is connected under each feeding structure 1. The two conveying and heating structures 2 are respectively provided at the two ends of the spray structure 3 and are respectively connected to the middle position of the spray structure 3. By providing two feeding structures 1 and conveying and heating structures 2, the efficiency of the metal powder being transferred to the spray structure 3 is greatly increased, which is beneficial to reducing the time interval of the cold flame eruption, so as to further realize instantaneous multiple eruptions.

[0033] See also Figure 3 The feeding structure 1 of the present application includes a hopper 5, a switch plate 6 and a transition hopper 7. The switch plate 6 is arranged at the lower end of the hopper 5 and connected to the outlet of the hopper 5. The transition hopper 7 is arranged below the hopper 5. The inlet of the transition hopper 7 corresponds to the outlet of the hopper 5. The outlet of the transition hopper 7 is connected to the conveying and heating structure 2. The hopper 5 is used to hold metal powder. It is in a bucket shape, which is also convenient for the leakage of metal powder. The switch plate 6 is used to block the outlet of the hopper 5. Specifically, the switch plate 6 can be moved away from the outlet of the hopper 5 and closed by the electromagnet structure 26 during operation to realize the storage and discharge of the hopper 5. The setting of the transition hopper 7 makes up for the disadvantage that the metal powder in the hopper 5 is easy to be oxidized at high temperature, resulting in poor effect, and avoids the possibility that the metal powder falls directly to the conveying and heating structure 2 and causes the metal powder to be oxidized. An opening 8 is opened on it, which is also convenient for operating the switch plate 6 through the opening 8.

[0034] Please continue reading Figure 3 The conveying and heating structure 2 of the present application includes a feeding motor 9, a driving gear 10, a driven gear 11, a feeding tube 12, a feeding screw 13 and a heating coil 14. The output end of the feeding motor 9 is fixedly connected to the driving gear 10, one end of the feeding screw 13 is fixedly connected to the driven gear 11, and the other end is located in the feeding tube 12. The driving gear 10 is meshed with the driven gear 11. A feeding port 15 is provided on the side of one end of the feeding tube 12. The feeding port 15 corresponds to the discharge end of the feeding structure 1, and the other end is flush with the feeding screw 13 and is connected to the middle position of the spray structure 3. The heating coil 14 is sleeved on the feeding tube 12. When the conveying and heating structure 2 is working, the feeding motor 9 drives the driving gear 10 to rotate, the driving gear 10 drives the driven gear 11 meshing therewith to rotate, and the driven gear 11 drives the feeding screw 13 to rotate. The metal powder is continuously transported from the feed port 15 to the spray structure 3 through the thread of the rotating feeding screw 13. The heating coil 14 is used to heat and ignite the metal powder in the feeding pipe 12. The whole is a mechanical transmission structure with the advantage of stable transmission effect. A bearing 24 is sleeved and connected to the outside of the feeding screw 13. The inner ring of the bearing 24 is sleeved on the feeding screw 13, and the outer ring is fixed. The setting of the bearing 24 realizes that the feeding screw 13 does not produce displacement when rotating and feeding.

[0035] Please continue reading Figure 3 The transmission heating structure 2 of the present application further includes a heat-insulating outer shell 16, which is sleeved on the outside of the heating coil 14. The provision of the heat-insulating outer shell 16 is conducive to preventing other structures of the product from being heated and damaged, and also reduces heat loss, so that the heating coil 14 can be quickly heated to the temperature at which the metal powder is ignited.

[0036] See also Figure 3-4 The continuous instantaneous jet structure 4 of the present application includes an air pump 17 and at least two jet structures 18. The air pump 17 is connected to the jet structure 18, and the jet structure 18 is connected to the spray structure 3. The air pump 17 inflates the jet structure 18. The jet structure 18 sprays at one end of the spray structure 3, so that the metal powder located in the middle of the spray structure 3 is sprayed out, thereby realizing the spraying of cold flames. In the present application, there are 3 jet structures 18, including but not limited to these, and can also be set to 4, 5 or more, which can be set specifically according to the frequency requirements for continuous instantaneous spraying.

[0037] Please continue reading Figure 4 The continuous instantaneous jet structure 4 of the present application also includes an air intake seat 19, a one-way valve 20 and a first three-way seat 21. The air intake seat 19 is respectively connected to the air pump 17 and the one-way valve 20. A pressure sensor 27 is provided on the air intake seat 19 for controlling the air pressure in the jet structure 18. The first three-way seat 21 is respectively connected to the one-way valve 20 and the three jet structures 18. The setting of the one-way valve 20 prevents the gas at the jet structure 18 from flowing back to the air pump 17, reducing the possibility of damage to the air pump 17. Further, the jet structure 18 includes a pressure tank 22 and a solenoid valve 23. The continuous instantaneous jet structure 4 also includes a second three-way seat (not shown). The air outlet of the pressure tank 22 is connected to the second three-way seat, and the second three-way seat is connected to the air inlet of the solenoid valve 23. The air outlet of the solenoid valve 23 is connected to the spray structure 3. The electromagnetic valve 23 is used to control the switch state of the pressure tank 22. When blowing is required, the electromagnetic valve 23 is opened, and the pressurized gas in the pressure tank 22 instantly ejects the ignited metal powder in the spray structure 3, realizing the instantaneous eruption of cold flames. The continuous multiple jets to the spray structure 3 can be achieved by speeding up the inflation efficiency of the pressure tank 22 by the air pump 17; more double shots can be achieved by increasing the number of jet structures 18. At the same time, only one pressure sensor 27 is required, which is conducive to reducing the complexity of the structural setting and the manufacturing cost.
